Code Overview

1. Header Files and Namespace:

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

2. Enumeration (enDayOfWeek)

• Defines seven values corresponding to the days of the week:
  • 1 → Saturday
  • 2 → Sunday
  • 3 → Monday
  • 4 → Tuesday
  • 5 → Wednesday
  • 6 → Thursday
  • 7 → Friday

3. User Input Function (ReadNumberInRange)

• Uses a do-while loop to ensure valid input within a given range.
• Prompts the user to enter a day number (1-7).
• Reads and returns the validated integer.

4. Day Selection Function (ReadDayOfWeek)

• Calls ReadNumberInRange() to get a day number (1-7).
• Converts the integer input into an enumeration value.
• Returns the corresponding enum day.

5. Day Conversion Function (GetDayOfWeek)

• Takes an enDayOfWeek value as input.
• Uses a switch statement to determine the day name.
• Returns the corresponding string representation.

6. Program Execution (main())

• Calls ReadDayOfWeek() to get user input.
• Calls GetDayOfWeek() to determine the day name.
• Prints the day name.
• Returns 0 to indicate successful execution.
