Thread: Need suggestions for more randomness

Hi, I'm working on a blackjack program and of course I need a random card draw function. Now the problem is I don't have one, it's I need to improve it

Code:

#include <iostream>
#include <cstdlib>
#include <cmath>
#include <ctime>
#include <string>
using namespace std;
int a;
int draw(int a);
int main(){
    draw(c);
    cin.ignore();
};
int draw(int a) {
    int b, c, e;
    string d;
  srand(time(0));
  b = rand() % 52;
  c = b % 4;
  e = b % 12;
  switch (c){
         case 0:
              d = "Hearts";
         case 1:
              d = "Diamonds";
         case 2:
              d = "Spades";
         case 3:
              d = "Clubs";
              }
  
  cout<< e << " of "<< d;
  
  return b;
};

The out put always has clubs as the suit. Any suggestions on how to improve the randomness?

Heh heh that would help....
