Thread: Command-line argument echoing in reverse

I am trying to echo the command line arguments. An example would be if you the user entered "a.out null and void" then it would echo back "void and null."

I have a program written to echo back exactly what the user enters but I can't think of a way to make it do it in reverse order. Here's the code I have:

Code:

int main(int argc, char *argv[])
   {
       int i;

       for (i = 1; i < argc; i++)
           printf("%s%s", argv[i], (i < argc-1) ? " " : "");
       printf("\n");
       return 0;
   }

Code:

#include <stdio.h>

int main(int argc, char *argv[])
{
    while (argc-- > 0)
        printf("%s ", argv[argc]);
    return 0;
}

k, thanks for the help.

You could also just reverse your for loop (initialise i to argc-1, count down to 1, subtract 1 from i each iteration).
