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 (float &A, float &B) to modify the values directly.
• Prompts the user to enter the width and length of a rectangle.

3. Area Calculation Function (CalculateRectangleArea)

• Takes the rectangle's width and length as input.
• Computes and returns the area using A * B.

4. Output Function (PrintResult)

• Receives the computed area as a parameter.
• Prints "Rectangle Area = [Area]".

5. Program Execution (main())

• Declares two float variables (A, B) to store width and length.
• Calls ReadNumbers() to get user input.
• Calls CalculateRectangleArea() to compute the area.
• Calls PrintResult() to display the result.
• Returns 0 to indicate successful execution.
