Chapter 9: File input/output
Storage of data in variables and arrays is temporary; all such data is lost when a program terminates. Files are used for permanent retention of large amounts of data. C views each file simply as a sequential stream of bytes. Each file ends with an end-of-file marker.The declaration for a file variable is
FILE *fp;
Before a file can be used, it must be opened using the function fopen, its syntax is fp = fopen( name, mode ); where fp: a pointer to the file structure for the file. A return of NULL means error. name: for writing. ds to the end of an existing file, open the file for appending. fclose( fp ) to close file when it is not needed anymore. feof( fp ) to check if the EOF is reached. The function feof returns a non-zero value as long as there are more entries unread in the file.Examples: ex103.c ex104.c ex105.c ex101.c ex102.c
Binary files The modes for binary files are exactly the same as those for text files, but with the letter
