Code Overview

1. Header Files and Namespace:

• <iostream> is included for input and output operations.
• <string> is included for potential future use (not used in this program).
• using namespace std; allows the use of standard functions without prefixing them with std::.

2. User Input Function (ReadNumbers)

• Uses reference parameters (int &Num1, int &Num2) to modify the values directly.
• Prompts the user to enter two numbers and stores them in the provided reference variables.

3. Swapping Function (Swap)

• Uses reference parameters (int &A, int &B) to swap values in place.
• Utilizes a temporary variable (Temp) to store one of the values during swapping.
• The swapping is performed without returning a value since the original variables are modified.

4. Output Function (PrintNumbers)

• Receives two integer values as parameters.
• Prints their values in the format:

Number1 = [value]
Number2 = [value]

5. Program Execution (main())

• Declares two integer variables (Num1, Num2).
• Calls ReadNumbers() to get user input.
• Calls PrintNumbers() to display values before swapping.
• Calls Swap() to swap the two values.
• Calls PrintNumbers() again to show values after swapping.
• Returns 0 to indicate successful execution.
