[Tutor] C program

[Tiger12506]

Hello people of the world.

This question is not a Python related question, but I thought I might just 
throw it in here and see if there are any C old-timers who could help out.

I have a string with space and I would like to remove the space before 
comparing but I don't know how to go about doing it. Here is the code

int result = strcmp("yes","yes ");//trailing space on the second yes
this should give me '0' meaning they are both the same, but with the space, 
it gives me '-1'

Please note: those arguments can be supplied by the user, and when they do, 
I want to strip off the trailing space.

Any helps is highly appreciated.
---------------------

I doubt if this is the best way, but you can do this.


/*--------------------------------------------------*/
#include <stdlib.h>
#include <stdio.h>

char s[20] = "yes";
char s2[20] = "yes      ";

void rstrip(char *c) {
  while (*c++!=0);
  c--;
  while (*--c==' ') *c = 0;
}

int main() {
  rstrip(s2);
  int result = strcmp(s, s2);
  printf("%d\n",result);
  system("pause");
}

PS - This *is* a python list. Usually the tutors don't like people who post 
off-topic stuff. (And C is pretty off-topic)
