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.

Understanding file operations for each type of stream

Because there are two types of file streams, text streams, and binary streams, there are also different sets of functions to manipulate them.

We have already seen most of the functions that are useful for text streams. They are as follows:

  • fprintf(): Writes formatted text to the output stream
  • fscanf(): Reads and interprets formatted text from the input stream
  • fputs(): Writes an unformatted line to the output stream
  • fgets(): Reads an unformatted line from the input stream

There are also some single-character functions that we have come across:

  • fgetc(): Reads a single character from the input stream
  • fputc(): Writes a single character to the output stream
  • ungetc(): Puts a single character back into the input stream

These single-character functions are particularly handy when processing the input of...
