I found it, here it is:


#include <stdio.h>

int main ( void )

{

static const char filename[] = "file.txt";

FILE *file = fopen ( filename, "r" );

if ( file != NULL )

{

char line [ 128 ]; /* or other suitable maximum line size */

 

while ( fgets ( line, sizeof line, file ) != NULL ) /* read a line */

{

fputs ( line, stdout ); /* write the line */

}

fclose ( file );

}

else

{

perror ( filename ); /* why didn't the file open? */

}

return 0;

}
