    What have you tried?
    C + C++ Compiler: MinGW port of GCC
    Version Control System: Bazaar

    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;
    }
