"Karl's *ARGV[] Example" by Karl

[Budgiekarl]

This for people who want to know what to do with 'int main(int argc, char *argv[])', I'm open to suggustions or corrections.

THX

So here it is!

//////////////////////////////
//  Karl's *ARGV[] Example
//         argv.c
//////////////////////////////
//
// This program prints the
// command line.
// 
// If you use DOS, compile this
// then type in 'argv', then run
// this program then you will see
// something like this:
// 
// Command Line:
// C:\stuff\argv.exe
// 
// If you use Windows, compile this
// then goto the start menu then
// goto 'programs' and click on
// 'MS-DOS Prompt', then type in:
// C:\stuff\argv
// Then you will see something like
// this:
// 
// Command Line:
// C:\stuff\argv.exe 
// 
// The Comments though-out the
// program will explain more
// about how this works.
// 
//////////////////////////////

#include <stdio.h> // Standard I/O

int main(int argc, char *argv[]) // *argv[] is a pointer that points to the strings on the command line
{
  int ctr; // Counter Variable
  
  printf("Command Line:\n");
  for(ctr=0;ctr<argc;ctr++) // 'argc' is the number of strings on the command line
  {
    printf("%s\n", argv[ctr]);
  }
  
  getchar();
  return 0;
}

printf("%s\n", argv[ctr]);

I'd use the following printf statement to display a little more information:
printf("argv[%d] = '%s' \n", cnt, argv[cnt]);

Otherwise, quite useful. I've used this type of program for years.
