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. Structure (strTaskDuration)

• Defines a struct to store task duration components:
  • NumberOfDays
  • NumberOfHours
  • NumberOfMinutes
  • NumberOfSeconds

3. 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 integer.

4. Task Duration Input Function (ReadTaskDuration)

• Calls ReadPositiveNumber() for each duration component.
• Returns a struct containing the task duration values.

5. Task Duration Conversion Function (TaskDurationInSeconds)

• Takes a struct with task duration components.
• Converts:
  • Days → Seconds using 1 day=24×60×601 \text{ day} = 24 \times 60 \times 601 day=24×60×60
  • Hours → Seconds using 1 hour=60×601 \text{ hour} = 60 \times 601 hour=60×60
  • Minutes → Seconds using 1 minute=601 \text{ minute} = 601 minute=60
  • Adds Seconds directly.
• Returns the total duration in seconds.

6. Program Execution (main())

• Calls ReadTaskDuration() to get user input.
• Calls TaskDurationInSeconds() to compute the total time in seconds.
• Prints the final result.
• Returns 0 to indicate successful execution.
