Thread: preprocessor directives

I'm assuming you've used google alread so:
not using vc++ so don't know about

Code:

#using

here is some the first I found on a site and modified it, the second I coded to test writing macros with the #define directive

Code:

  /**
 ** This example illustrates some predefined macros.
 **/
 
#pragma langlvl(ANSI)
#include <stdio.h>
 
#if __STDC__
#   define CONFORM    "conforms"
#else
#   define CONFORM    "does not conform"
#endif


 
int main(void)
{
  system("TITLE C macros");
  printf("Line %d of file %s has been executed\n", __LINE__, __FILE__);
  printf("This file was compiled at %s on %s\n", __TIME__, __DATE__);
  printf("This program %s to ANSI/ISO standard C\n", CONFORM);
   system("vol");
  getchar();
  return 0;
}

Here is one site that talks about macros.
