Write a character to a stream
#include <stdio.h>

- The character that you want to write.
- fp
- The stream you want to write the character on.

Use the -l c option to

to link against this library.
This library is usually included automatically.
The putc() macro writes the character c,
cast as (int)(unsigned char), to the
output stream designated by fp.
The character written, cast as (int)(unsigned char),
or EOF if an error occurs
(errno is set).

fp = fopen( "file", "r" );
if( fp != NULL ) {
while( (c = fgetc( fp )) != EOF ) {
putc( c, stdout );
}
fclose( fp );

return EXIT_SUCCESS;
