Question

My program looks like that

/* print_it.c—This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>

void do_heading(char *filename);

int line = 0, page = 0;

int main( int argv, char *argc[] )
 {
 char buffer[256];
 FILE *fp;

 if( argv < 2 )
 {
 fprintf(stderr, “\nProper Usage is: “ );
 fprintf(stderr, “\n\nprint_it filename.ext\n” );
 return(1);
 }

 if (( fp = fopen( argc[1], “r” )) == NULL )
 {
 fprintf( stderr, “Error opening file, %s!”, argc[1]);
 return(1);
 }

 page = 0;
 line = 1;
 do_heading( argc[1]);

 while( fgets( buffer, 256, fp ) != NULL )
 {
 if( line % 55 == 0 )
 do_heading( argc[1] );

 fprintf( stdprn, “%4d:\t%s”, line++, buffer );
 }

 fprintf( stdprn, “\f” );
 fclose(fp);
 return 0;
 }

 void do_heading( char *filename )
 {
 page++;

 if ( page > 1)
 fprintf( stdprn, “\f” );

 fprintf( stdprn, “Page: %d, %s\n\n”, page, filename );
 }

Using Win 8 + VS 2012. To compile this, opened Developer Command Prompt, and typed

cl print_it.c

Got this screen (bunch of errors and warnings)

What am I missing?

It looks like you carelessly copy-pasted. Start by replacing every “ and ” with ".

Then remove this:
