#include <iostream> 
using namespace std; 
 
int main() { 
  double result, n, d; 
 
  cout << "Enter value: "; 
  cin >> n; 
 
  cout << "Enter divisor: "; 
  cin >> d; 
 
  if(d != 0) { 
    cout << "d does not equal zero so division is OK" << "\n"; 
    result = n / d; 
    cout << n << " / " << d << " is " << result; 
  } 
 
  return 0; 
}

Enter value: 12
Enter divisor: 21
d does not equal zero so division is OK
12 / 21 is 0.571429"
