putc[edit | edit source]

#include <cstdio>
int putc( int ch, FILE *stream );

The putc() function writes the character ch to stream. The return value is the character written, or EOF if there is an error. For example:

int ch;
FILE *input, *output;
input = fopen( "tmp.c", "r" );
output = fopen( "tmpCopy.c", "w" );
ch = getc( input );
while( ch != EOF ) {
  putc( ch, output );
  ch = getc( input );
fclose( input );
fclose( output );

Generates a copy of the file tmp.c called tmpCopy.c.
