Learn C Programming

By: Jeff Szuhay

Overview of this book

C is a powerful general-purpose programming language that is excellent for beginners to learn. This book will introduce you to computer programming and software development using C. If you're an experienced developer, this book will help you to become familiar with the C programming language. This C programming book takes you through basic programming concepts and shows you how to implement them in C. Throughout the book, you'll create and run programs that make use of one or more C concepts, such as program structure with functions, data types, and conditional statements. You'll also see how to use looping and iteration, arrays, pointers, and strings. As you make progress, you'll cover code documentation, testing and validation methods, basic input/output, and how to write complete programs in C. By the end of the book, you'll have developed basic programming skills in C, that you can apply to other programming languages and will develop a solid foundation for you to advance as a programmer.

Reading names and writing names

To begin developing the createUnsorted.c program, first copy the getoptFiles.cfile to the createUnsorted.c file. We will henceforth modify this file.

Open createUnsorted and, after the const int stringMax declaration, add the following function prototypes:

void  usage(   char* cmd );
int getName( FILE* inFileDesc , char* pStr );
voidputName( char* nameStr ,FILE* outFileDesc );
int trimStr( char* pString );

In this chapter, for each program, we will follow the following general program organization:

  • #include files
  • Constant declarations
  • struct and enum declarations
  • Function prototypes
  • main()
  • Function definitions (these generally appear after main() in the same order as their prototype declarations)

This is merely a convention. In the next chapter, we will learn about a multi-file program organization that will help to...
