/*
Objective:
Create a program that acts as a simple calculator.
The program should allow the user to choose a mathematical
operation from a menu, input two numbers, and then display the result.
The selection of operations should be handled using a switch-case statement.

Requirements:
Menu of Operations:

1: Addition (+)
2: Subtraction (-)
3: Multiplication (*)
4: Division (/)
5: Exit
Input:

The user selects an operation from the menu by entering a number (1-5).
The program then prompts the user to input two numbers for the calculation.
Calculation:

Perform the chosen operation on the two numbers.
For division, ensure that the second number is not zero. If zero is entered,
display an error message.
Exit:

The program should loop until the user selects "5: Exit".
