Who’s This Book For? What Makes This Book Different? This Book’s Design Elements How Can I Have Fun with C? What Do I Do Now?

Part I: Jumping Right In

1. What Is C Programming, and Why Should I Care?

What Is a Program? What You Need to Write C Programs The Programming Process Using C

2. Writing Your First C Program

A Down-and-Dirty Chunk of Code The main() Function Kinds of Data Wrapping Things Up with Another Example Program

3. What Does This Do? Clarifying Your Code with Comments

Commenting on Your Code Specifying Comments Whitespace A Second Style for Your Comments

4. Your World Premiere—Putting Your Program’s Results Up on the Screen

How to Use printf() Printing Strings Escape Sequences Conversion Characters Putting It All Together with a Code Example

5. Adding Variables to Your Programs

Kinds of Variables Naming Variables Defining Variables Storing Data in Variables

6. Adding Words to Your Programs

7. Making Your Programs More Powerful with #include and #define

Including Files Placing #include Directives Defining Constants Building a Header File and Program

8. Interacting with Users

Looking at scanf() Prompting for scanf() Problems with scanf()

Part II: Putting C to Work for You with Operators and Expressions

9. Crunching the Numbers—Letting C Handle Math for You

Basic Arithmetic Order of Operators Break the Rules with Parentheses Assignments Everywhere

10. Powering Up Your Variables with Assignments and Expressions

Compound Assignment Watch That Order! Typecasting: Hollywood Could Take Lessons from C

11. The Fork in the Road—Testing Data to Pick a Path

Testing Data Using if Otherwise...: Using else

12. Juggling Several Choices with Logical Operators

Getting Logical Avoiding the Negative The Order of Logical Operators

13. A Bigger Bag of Tricks—Some More Operators for Your Programs

Goodbye if...else; Hello, Conditional The Small-Change Operators: ++ and -- Sizing Up the Situation

Part III: Fleshing Out Your Programs

14. Code Repeat—Using Loops to Save Time and Effort

while We Repeat Using while Using do...while

15. Looking for Another Way to Create Loops

for Repeat’s Sake! Working with for

16. Breaking in and out of Looped Code

Take a break Let’s continue Working

17. Making the case for the switch Statement

Making the switch break and switch Efficiency Considerations

18. Increasing Your Program’s Output (and Input)

putchar() and getchar() The Newline Consideration A Little Faster: getch()

19. Getting More from Your Strings

Character-Testing Functions Is the Case Correct? Case-Changing Functions String Functions

20. Advanced Math (for the Computer, Not You!)

Practicing Your Math Doing More Conversions Getting into Trig and Other Really Hard Stuff Getting Random

Part IV: Managing Data with Your C Programs
