Answer to Question #300882 in C++ for Kelly

Question

How to execute this using vector

#include <cstdlib>

#include <ctime>

#include <iostream>

int main() {

int dice[6] = {0};

srand(time(0));

for (int ctr = 0; ctr < 10000; ctr++) {

switch ((rand() % 6) + 1) {

case 1:

dice[0] += 1;

break;

case 2:

dice[1] += 1;

break;

case 3:

dice[2] += 1;

break;

case 4:

dice[3] += 1;

break;

case 5:

dice[4] += 1;

break;

case 6:

dice[5] += 1;

break;

}

}

for (int index = 0; index < 6; index++)

std::cout << index + 1 << " appears " << dice[index] << " time/s\n";

return 0;

}
