Question

Create a function that takes two numbers and a mathematical operator +, –, / , * and will perform a calculation with the given numbers.

Examples:

calculator(2, "+", 2) ➞ 4

calculator(2, "*", 2) ➞ 4

calculator(4, "/", 2) ➞ 2

Notes If the input tries to divide by 0, return: "Can't divide by 0!"

        {
                case '+'://addition operatiob
                        cout << num1 + num2;
                        break;
