   fopen(), getc(), putc(), exit(), fclose() fprintf(), fscanf(), fgets(), fputs() rewind(), fseek(), ftell(), fflush() fgetpos(), fsetpos(), feof(), ferror() ungetc(), setvbuf(), fread(), 

In this chapter, you learn how to process files using C's standard I/O family of functions. You learn about text modes and binary modes, text and binary formats, and buffered and nonbuffered I/O. You practice using functions that can access files both sequentially and randomly .

Files are essential to today's computer systems. They are used to store programs, documents, data, correspondence, forms, graphics, and myriad other kinds of information. As a programmer, you will have to write programs that create files, write into files, and read from files. In this chapter, we show you how.
