c programming using stack

use recursion to reverse the string.

Code:

#include <stdio.h>

void reverseString (const char * s) {
  if (*s) {
    reverseString(s + 1);
    fprintf(stdout, "%c", s[0]);
  }
}

int main (int argc, char ** argv) {
  reverseString("G4143 can you reverse this?");
  fputs("\n", stdout);
  reverseString("How about this?");
  fputs("\n", stdout);
  return 0;
}
