Introduction

A program to list the command line arguments

Demo Code

#include <stdio.h>

int main(int argc, char *argv[]){
  printf("Program name: %s\n", argv[0]);
  for(int i = 1 ; i<argc ; ++i)
    printf("Argument %d: %s\n", i, argv[i]);
  return 0;//  w  ww.  ja  va  2  s .co m
}

My source file for this program had the name Main.c, so I entered the following command to execute it:

Main first second_arg "Third is this"

Putting double quotes around the argument ensures that it is read as a single argument and not as three arguments.
