Write a lucky pick program

May i know how to write a lucky pick program in dos mode.

got a group of number 1 to 52. got 6 group to select it. and each time when the group get the number it will obliterate it from the number group.

What have you tried?

actually i'm newbie i dun know where should i start.

That's a shame.

Do you know how to pick numbers randomly?
Do you know how to check whether one number is the same as another number?

here's one that uses the "Fischer-Yates shuffle":

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main() {
        int x, ray[52], i, y, tmp;
        for (i=0;i<52;i++) ray[i]=i;
        srand(time(0));
        for (i=51;i>=0;i--) {
                x=RAND_MAX/(i+1);
                y=rand(); y/=x;
                if (y==i) continue;
                tmp=ray[i];
                ray[i]=ray[y];
                ray[y]=tmp;
        }
        for (i=0;i<6;i++) printf("%d\n",ray[i]);
        return 0;
}
