write a string to stdout
#include <stdio.h> int puts( const char *buf );
The puts() function writes the character string pointed to by buf to the output stream designated by stdout, and appends a newline character to the output. The terminating null character isn't written.
A nonnegative value (which is the number of characters read, including newlines), or EOF if an error occurs. When an error has occurred, errno indicates the type of error detected.
#include <stdio.h>
void main()
{
FILE *fp;
char buffer[80];
fp = freopen( "file", "r", stdin );
while( gets( buffer ) != NULL ) {
puts( buffer );
}
fclose( fp );
}
