calculator.cpp

Write a program that prompts the user to select an arithmetic operator and two numbers. The program will calculate and display the result based on the selected operator.

Input validation: decide how the program should handle an illegal input for the arithmetic operator selection.

Sample run 1

Enter an operator (+, -, * or /): /

Enter two numbers separate with a space: 25 2

25 / 2 = 12.50

Sample run 2

Enter an operator (+, -, * or /): *

Enter two numbers separate with a space: 9 15

9 * 15 = 135.00
