Is this what I am supposed to do for the calculator app?
// app variables
var strOperator = "+"
var num1 = 3
var num2 = 4
switch strOperator {
case "+":
print("Addition")
case "-":
print("Subtraction")
case "*", "x":
print("Multiplication")
case "/":
print("Division")
case "^":
print("Power")
default:
print("Undefined operator")
}
