This was the first book I read for c# and it got me going in the right direction and it was Free Ebooks Where should I download Let Us C 15th edition PDF?.

This book got me up to speed in no time for my first large scale C development project at work—I highly recommend it. The mini-games that guide you through the different programming challenges will definitely stick the knowledge to your brain. A great learn-by-doing book! The many coding challenges keep it fun, even when the concepts are tough. If you want to learn C in depth and have fun doing it, this is THE book for you. Head First C will guide beginners of all sorts to a long and productive relationship with C and the.

Resources that are better spent storing the really big things. Like the danger of fire. And ate ner ge and both ns. It als s they relate to. Use casual lan l stories instead of lec Tel e.

Pu o makes things more than on transfer studies. You remember ent on its emotional con nd pe de ely g larg is kin something ing. The amazing thing is. To get the most from this book. We were expected to learn. But pictures and conversational style are just the beginning. On the other hand. So just how DO you get your brain to treat C like it was a hungry tiger?

The things on the previous page are a big part of the solution. For example. If you want to use what you read in this book. As important as a tiger. You obviously know that you are able to learn and remember even the dullest of topics if you keep pounding the same thing into your brain.

Learn how you learn. And for that. Most of us did not take courses on metacognition or learning theory when we were growing up. Crucial to your well-being. With enough repetition. The slow way is about sheer repetition. No need to stay awake. Think about how you think.

Your brain on this content. But regardless of your own learning preference. We used multiple learning styles. We used a personalized. And we made the paper puzzles and code exercises challenging-yet-do-able. In stories. We used people. We used concepts and pictures in unexpected ways because your brain is tuned for novelty. And we included stories and exercises that present more than one point of view. You can use one blueprint to make any number of houses. Since working one side of the brain often means giving the other side a chance to rest.

And your brain pays more attention to people than it does to things. We used redundancy. We included challenges. That which causes you to feel something is more likely to be remembered. And when text and pictures work together. We include content for both sides of your brain. We used pictures.

We included dozens of activities. Dehydration which can happen before you ever feel thirsty decreases cognitive function. When the book asks you a question.

Better still. The more deeply you force your brain to think. Make up your own captions for the photos. That means all of them. Stop and think. And definitely get it working before you move on to the next part of the book. Once you go past a certain point. Try new things. If you put in something new during that processing time. Out loud. We put them in. Get involved with the stories. Use a pencil.

Pay attention to whether your brain is getting overloaded. But try to solve the problem before you look at the solution. Coding is a skill. Lots of it. The rest is up to you. Your brain works best in a nice bath of fluid.

Part of the learning especially the transfer to long-term memory happens after you put the book down. Feel something. Imagine that someone really is asking the question.

Your brain needs to know that this matters. The more you understand.

Your brain needs time on its own. If you find yourself starting to skim the surface or forget what you just read. Groaning over a bad joke is still better than feeling nothing at all.

Write your own notes. Cut this out an ick it on your refrigerdatst or. Or at least the last challenging thing. These tips are a starting point. Ultimate or Test Professional editions.

All of the screenshots that you see throughout the book were taken from those two editions of Visual Studio. But we definitely understand that some of our readers may not be running it—for example. It installs cleanly alongside other editions. The screenshots in this book match Visual Studio Express Edition. You can also use Visual Studio Professional.

So we know you want to get your hands dirty right away. We gave you a lot of opportunities to sharpen your skills by putting exercises in every chapter. If you see the Pool Puzzle logif the activity is optional. And the first time through.

The redundancy is intentional and important. One distinct difference in a Head First book is that we want you to really get it.

In some of the Brain Power questions you will find hints to point you in the right direction. But when you see the Exercise logo with the running shoes. Some of them are to help with memory. The puzzles and activities are not add-ons. The activities are NOT optional.

Dr this. Point The language is flexible and easy to learn. It handles all the grunt work for you: The IDE lets you just focus on your program. You can leave mundane coding tasks to the IDE and focus on what your code should accomplish.

You can build full-featured professional programs without having to spend hours writing a graphical user interface entirely from scratch. The IDE does a lot for you. Creating programs in C is a snap. There are several project types to choose from. If you select Save. Things may look a bit different in your IDE. Go ahead and start up Visual Studio for Windows 8. What Visual Studio does for you… As soon as you save the project.

It creates several other files as well! You can see them in the Solution Explorer window. Expand Visual C and Windows Store. This file contains the XAML code that defines the user interface of the main page. It adds these to the Solution Explorer window. Skip over the start page and select New Project from the File menu. The screenshot on page 4 is in the Dark color theme.. See if you can guess what all of these things are for.

If you like it. You should be able to figure out the purpose of many of these windows and files based on what you already know. The designer lets you edit the user interface by dragging controls onto it. This is the toolbox. The Toolbox window has auto-hide turned on by default.

See this little pushpin icon? If you click it. It has a bunch of visual controls that you can drag onto your page.

This pane wi t abou lots of diagnostic info your app. You may have some different things written down. This particular Ellipse tag has three properties: The IDE is great at automatically generating some code for you.

You can change it. But the hard part of programming—figuring out what your program needs to do and making it do it—is something that no IDE can do for you. The IDE is set up to create code based on the way the element you dragged or added is most commonly used. What gives? Visual Studio will generate code you can use as a starting point for your applications. What is XAML. So if the IDE writes all this code for me. Everything the IDE does for you—every line of code it creates.

If you click on the Reset Window Layout command under the Window menu. Not good! Aliens are beaming up humans. Are you up to the challenge?

More and more evil aliens will fill up the screen. The people of planet Earth need you to build an awesome C app to coordinate their escape from the alien menace. Our greatest human scientific minds have invented protective interdimensional diamond-shaped portals to protect the human race. If you drag your human into one. Each human that the player has to save is drawn using a StackPanel. The app uses to provide ga controls for the playe meplay r. It sounds like a lot of work.

No problem. You can download a free PDF with details and instructions from http: With PDF. Deployment Pack age. The first two chapters and the last half of this book have many projects that are built with Visual Studio for Windows 8. Type Save the Humans as the project name. It looks like a blank page with a default black background. Double-click on MainPage. Visual Basic. Use these three buttons to turn on the grid lines. Choose New Project from the File menu.

You can fix this by closing the solution and starting over. Your starting point is the Designer window. These are the opening and closing tags for a grid that contains controls. Flip the page to keep going! This part of the project has steps numbered Looking to learn WPF? Look no further! When you add rows. Go to the Solution Explorer window and find..

If you chose a different name when you created your project. When you start a Windows Store app.. Go back to the Solution Explorer and right-click on it should be the second item in the Solution Explorer to select the project. Rightclick on it and choose Delete to delete the MainPage. You can do this all by hand with XAML. Choose Basic Page to add a new page to your projcet based on the Basic Page template. When you replace MainPage. Choose Basic Page and give it the name MainPage. It might display either or.

Rebuilding the solution brings everything up to date so it can display the page in the designer. The IDE will prompt you to add missing files—choose Yes to add them. Make sure you name it MainPage.

Then click the Add button to add the replacement page to your project. Your page should be displayed in the designer. Wait for the designer to finish loading. You can turn them on and off with the button. Throughout this book. Start defining rows by hovering over the border until a line and triangle appear: After the row is added. But it looks like I already have many rows and and columns in the grid.

I wanted to learn about C. What are those gray lines? Wait a minute.. The gray lines were just Visual Studio giving you a grid of guidelines to help you lay your controls out evenly on the page.

None of the lines you see in the designer show up when you run the app outside of Visual Studio.. Seeing all three of these will give you a deeper understanding of programming with C. But when you clicked and created a new row.

Windows Store apps need to look right on any screen.. Hover over the border of the grid until an orange triangle and line appear. Your grid rows and columns are now added! XAML grids are container controls. The humans are preparing. Grids consist of rows and columns that define cells. A grid is a great way to lay out a page. Now the column widths and row heights match the numbers on the top and side of your page. You can set the rows and columns of a grid to a specific pixel height.

Set the width of the left column. For now. Hover over the number above the first column until a dropdown menu appears. Set your columns or rows to Pixel to give them a fixed width or height. The Star setting lets a row or column grow or shrink proportionally to the rest of the grid.. If you remove the Width or Height property. Choose Pixel to change the star to a lock. But you can also use the Star setting. Make the right column and the bottom row by choosing Pixel and typing into the box.

By the end of the book. You added three columns and three rows. XAML and C are case sensitive! Make sure your uppercase and lowercase letters match example code. It might adjust the other columns. You used the column and row drop-downs to set the Width and Height properties.

If it did. Click on the number above the center column and enter 1. In a minute. This top row with a height of pixels is part of the Basic Page template you added. This is how a column is defined for a XAML grid. If it does. These are properties. Use the pushpin to keep it from collapsing. Click on Pointer in the toolbo then click on the TextBlock x. Your XAML will look something like this. The XAML for the button starts here. See if you can figure out how it determines which row and column the controls are placed in.

You can add line breaks too. Those are called controls. Drag a into the lower-right cell of the grid. Give it a try! Each property has a name. Try clicking this button. It brings up the Document Outline window. Try clicking in both the grid and the XAML window to select different controls. You dragged a ContentControl into the same cell.

When you add the Canvas control. If not. Can you figure out how to use it? Drag a into the bottom-center cell. What do you think it does? Look in the XAML window: You just added this ProgressBar.

When you drag a control out of the toolbox and onto your page. When you edit the text in the button. You might need to expand the Common and Layout sections. Right-click on the button control that you dragged onto the grid and choose Edit Text from the menu.

This works for other things in the IDE. When you dragged the button onto the page. Use it to change the name of the control to startButton and center the control in the cell. Change the text to: Change the text of the button. The Properties window in the IDE lets you change the look and even the behavior of the controls on your page. These little squares tell you if the property has been set. Click on the square and choose Reset from the menu to reset the margins to 0. Make sure the button is selected in the IDE..

Use the Name box to change the name of the control to startButton. While you have the ContentControl selected. Choose from the pop-up menu. Wait a minute! The Blank Page template uses a static resource called AppName for the name that it displays at the top of the page.

Then right-click on it. Click and drag to select both the TextBlock and ContentControl. The StackPanel is a lot like the Grid and Canvas: Now you should see the correct text at the top of the page: If you selected the wrong thing. Make sure that the TextBlock is near the top of the cell. A box appears around the StackPanel if you hover over it. Your TextBlock and ContentControl are in the lower-right cell of the grid. But since you dragged the Right-click and TextBlock to the top of the cell and the ContentControl to the bottom.

You can also hit Escape to deselect the control. You can select the StackPanel by clicking between the two controls. Click in the middle of the StackPanel of the StackPanel.

You are here! This adds a new control to your form: Do it several times to undo the last few changes. Once you change the name.. Right-click on the ProgressBar in the bottom-center cell of the grid. Then set its Column to 0. Then click on the righthand tab and choose the ending color. Choose the starting and ending colors for the gradient by clicking each of the tabs at the bottom of the color editor and then clicking on a color. Then use the and buttons in the Properties window to set its vertical and horizontal alignments to Stretch.

Use the Height box in the Layout section of the Properties window to set the Height to Click on to select the Canvas control.

Make sure the Canvas control is selected.. Remember that Canvas control that you dragged into the center square? Click on the lefthand tab. It should be right below the AppName resource..

That will keep the template selected. You can also use the Document Outline window to select the grid if it gets deselected. Choose Edit Template. Click in this color selector and drag to the upper-right corner. Then do the same for the TextBlock.

Select the StackPanel control. Your newly created template is currently selected in the IDE. If you accidentally click out of the control template.

Name it EnemyTemplate. Add a red circle to the template: Flip the page for the last steps.. XAML gives us templates.

Your game will have a lot of enemies bouncing around the screen. Your template is still invisible. Go back to the Document Outline if you see at the top of the Document Outline window.. Right-click on the Ellipse. The first option is to follow the next three paragraphs.

Select the Ellipse. If you change the Left and Top properties. Then use the Name box at the top of the window to set its name to human. Use the Document Outline window to select the Stack Panel make sure you see at the top of the Properties window.

Select the Canvas control. Click both buttons to set the Width and Height to Auto. The Rectangle will be added right on top of the Ellipse. Select the Canvas control again and double-click on Rectangle. Can you the shapes tha d or remove it? The second. Go back to the Document Outline window to see how your new controls appear: Hold down the Shift key and click on the Ellipse so both controls are selected.

Then select the Rectangle. Turn your rectangle into a diamond by rotating it 45 degrees. Open the Transform section of the Properties window to rotate the Rectangle 45 degrees by clicking on and setting the angle to Use the button in the Brushes section of the Properties window to give it a gradient.

Set its Height and Width properties to See if you can work out which property does what. Visual Studio gave you useful tools for laying out your page.

You set up the grid that will serve as the basis of your page. That will lay the groundwork to build out the rest of the game.. To make the game work.. You used a template to make the enemies look like red circles.. A lot of programmers build their code in small increments. Hover over the blue box and click the icon that pops up. See if you can find it. Notice the red squiggly line underneath the text you just typed? And the IDE generated it for me? What do you think will happen if you click it?

Go ahead and click it to find out! A method is just a named block of code. You should see some code pop up that looks like this: When you double-clicked on the Button control. The IDE will add code to your project that gets run any time a user clicks on the button. If you click on the squiggly line. Choose ContentControl from the list. If you miss one. The IDE generated a method stub for you: C code must be added exactly as you see it here.

Type the word Content into the method body. Select this and delete it. This is called a field. Change the parameter p1 to from. Do you see a squiggly underline under playArea? Edit the top line of the method to change the last three parameters. Then change any int types to double.

This time it added four parameters called enemy. Flip the page to see your program run! This line adds your new enemy control to a collection called Children.

The ones under AnimateEnemy will go away when you generate its method stub. You generated the method stub for the AnimateEnemy method on the previous page. Add one more to the bottom of the list: Statements like these let you use code from.

All of the code you need to get your program working is in these pages. Scroll all the way to the top of the file. Look over your code. NET libraries that come with C. The IDE generated several lines that start with using.

The IDE will jump your cursor to the right place to help you track down the problem. It makes an enemy start bouncing across the screen. This code makes the enemy you created move across playArea. This using statement lets you use code from the. If you change 4 and 6. Add code that creates an enemy bouncing animation.

The IDE helps you track down problems. All you need to do is finish your AnimateEnemy method. NET Framework animation program to move the enemies on in your your screen. If you still have some of those red squiggly lines. You probably just need to track down a typo or two. Each time you click it. Find the button at the top of the IDE. You may be missing parentheses or keywords. This button starts your program.

This starts your program running. Click the square to stop the program running. This big X is the splash screen. The button in the toolbar has been replaced with break.

EndTheGame This step is where we write C code that makes the gameplay run. Visual Studio can generate code for you. Name Use this when you want text or graphics in your control of the Remember how you set the Name at set its Th? The IDE will pop up another box: Press Tab one more time.

Add three more lines: As soon as you type the dot. These are fields. Tick Tick Tick Put your cursor right after the semicolon. Go up to the top of the file where you added that Random line. Choose Tick from the IntelliSense window and type the following text.

This game adds more and more enemies. The MainPage. The IDE generated a method for you called an event handler. Find this code that the IDE generated: Add these three lines below the one you added before. Press the Tab key. The IntelliSense window might not seem quite right: Notice how progressBar has an error? How does that change the gameplay? Try changing these numbers once your game is finished. Right now your Start button adds bouncing enemies to the play area.

If you get stuck. Generate a method stub for the StartGame method. Find the code you added earlier to make the Start button add an enemy.

Change it so it looks like this: When you change this line. This will get you used to entering code. Just go to the Head First Labs web page—we made it really easy for you to copy and paste all of the code in this program.

Did you forget to set the names of the target Rectangle or the human StackPanel? You can look a few pages back to make sure you set the right names for all of the controls. One misplaced comma or semicolon can cause two. Our spies have reported that the humans are building up their defenses!

The play area slowly starts to fill up with bouncing enemies. When the progress bar at the bottom fills up. The target timer should fill up slowly. If the timing is off. Flip the page to find out! Then go to the Properties window and press the button to switch it to show event handlers.

It also generated a method stub for you. Double-click in this box. Find the PointerPressed row and double-click in the empty box.. The Document Outline may have collapsed [Grid]. If you go back to the designer and click on the StackPanel again. These two vertical bars are a logical operator. You added a PointerPressed event handler to the human. Then you can add these event handlers to playArea: Be really careful and get them right.

Make sure you put the right code in the correct event handler! You can make the game more or less sensitive by changing these 3s to a lower or higher number. Use the Document Outline window to select the Rectangle named target.

Then press Tab again to generate the stub for your event handler: Now you can go to the new method that the IDE generated for you and fill in the code: Go to your AddEnemy method and add one more line of code to the end. Find File. Download ZIP. Sign in Sign up.
