I may have posted something along these lines before, but I cannot seem to find the answer to my question in any of my previous posts. I have a program from a teach yourself C book, and am having an error. The program is supposed to print a program listing with line numbers and I got it to work at one point but can't seem to do it now.
here is the code
Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>
void do_heading(char *filename);
stdprn = open(USB001, O_WRONLY);
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 );
}
Whenever I try to compile it using gcc, I get this error:
printit.c:8: error: expected identifier or '(' before '&' token
As I am just starting out with C, I would greatly appreciate any help with this. Thanks a bunch.
