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 (ReadTotalSales)

• Prompts the user to enter the total sales amount.
• Reads and returns the value as a float.

3. Commission Calculation Function (GetCommissionPercentage)

• Takes the total sales amount as input.
• Determines the commission percentage based on sales brackets:
  • ≥ 1,000,000 → 1%
  • 500,000 - 999,999 → 2%
  • 100,000 - 499,999 → 3%
  • 50,000 - 99,999 → 5%
  • Below 50,000 → 0%
• Returns the commission percentage.

4. Total Commission Calculation Function (CalculateTotalCommission)

• Uses the commission percentage to compute the total commission amount: Total Commission=Total Sales×Commission Percentage\text{Total Commission} = \text{Total Sales} \times \text{Commission Percentage}Total Commission=Total Sales×Commission Percentage
• Returns the computed total commission.

5. Program Execution (main())

• Calls ReadTotalSales() to get user input.
• Calls GetCommissionPercentage() to determine the commission rate.
• Calls CalculateTotalCommission() to compute the commission amount.
• Prints the commission percentage and total commission.
• Returns 0 to indicate successful execution.
