• create a program that will simulate a calculator
• that does the four basic mathematical operations (addition, subtraction, multiplication, and division)
• ask the user to submit two numbers and assign those numbers to two different variables
  • the variables will be integers and be named number1, and number 2
• display the four operations available
• then, ask the user which operation they want to do
  • use a decision structure (switch or if/else)
  • compute the answer, using the correct formula
• display the answer in a sentence
• save your file as calculator.cpp
• run your program four times, so you can all four operations for accuracy (what happened when you did division? Integer division usually gives an incorrect answer.).
• to solve division issue, you have two choices:
  • change variable type for number1 and number2 to double
  • use typecasting just for division
