Code Overview

1. Header Files and Namespace:

• <iostream> is included for input and output operations.
• <string> is included for handling message prompts.
• using namespace std; allows the use of standard functions without prefixing them with std::.

2. Enumeration (enOperationType)

• Defines four possible arithmetic operations:
  • + → Addition
  • - → Subtraction
  • * → Multiplication
  • / → Division

3. User Input Function (ReadNumber)

• Takes a custom message as input.
• Prompts the user to enter a floating-point number.
• Reads and returns the number.

4. Operation Selection Function (ReadOpType)

• Prompts the user to enter an operation type.
• Reads a single character (+, -, *, /).
• Converts and returns it as an enOperationType enum.

5. Arithmetic Calculation Function (Calculate)

• Takes two numbers and an operation type as input.
• Uses a switch statement to perform the selected operation:
  • Addition (+)
  • Subtraction (-)
  • Multiplication (*)
  • Division (/)
• Returns the computed result.

6. Program Execution (main())

• Calls ReadNumber() twice to get two input numbers.
• Calls ReadOpType() to determine the arithmetic operation.
• Calls Calculate() to compute and print the result.
• Returns 0 to indicate successful execution.

This structured explanation ensures clarity and ease of understanding.
