#include <iostream>
using namespace std;

int main() {

int num1, num2;
char choice;

cout << ”Enter First Number: “;
cin >> num1;

cout << “Enter Second Number: “;
cin >> num2;

cin >> choice;

switch(choice) {
case ‘+’ :
cout << “Your choice is addition, the answer is: “ << num1 + num2 ;
break;

case ‘-’ :

cout << “Your choice is subtraction, the answer is: “ << num1 - num2 ;
break;

case ‘*’ :
cout << “Your choice is multiplication, the answer is: “ << num1 * num2 ;
break;

case ‘/’ :
cout << “Your choice is division, the answer is: “ << num1 / num2 ;
