Code Overview

1. Header Files and Namespace:

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

2. User Input Function (ReadPositiveNumber)

• Uses a do-while loop to ensure positive input.
• Prompts the user to enter a valid number.
• Reads and returns the validated floating-point number.

3. Time Conversion Functions

4. Program Execution (main())

• Calls ReadPositiveNumber() to get user input for hours.
• Converts:
  • Hours to Days
  • Days to Weeks
• Displays:
  • Total Hours
  • Total Days
  • Total Weeks
• Returns 0 to indicate successful execution.
