#include <iostream>  
#include <ctime>
using namespace std;  
int main() {
   srand(time(0)); 

   int randNum = (rand() % 5 + 1 ); 

   switch(randNum){
    case 1: 
        cout << "You win a gummy bear\n"; 
        break; 
    case 2:
        cout << "You win an Apple Watch\n";
        break; 
    case 3: 
        cout << "You win an iPhone\n"; 
        break; 
    case 4: 
        cout << "You win a mouse\n";
        break; 
    case 5: 
        cout << "You win an AirPods\n";
        break; 
           
    }

}

In this code, I used the rand function in C++ to randomize every case in the switch functions.
