Code Overview

1. Header Files and Namespace:

• <iostream> is included for input and output operations.
• <string> is included for potential future use (though not needed in this program).
• using namespace std; allows the use of standard functions without prefixing them with std::.

2. Enumeration Definition (enPassFail)

• Defines:
  • Pass = 1 (for marks 50 and above)
  • Fail = 2 (for marks below 50)

3. User Input Function (ReadMark)

• Prompts the user to enter their exam mark.
• Reads and returns the entered mark.

4. Evaluation Function (CheckMark)

• Takes an integer mark as input.
• Returns:
  • enPassFail::Pass if the mark is 50 or greater.
  • enPassFail::Fail if the mark is below 50.

5. Output Function (PrintResults)

• Calls CheckMark() to evaluate the mark.
• Prints "You Passed" if the mark qualifies as a passing grade.
• Prints "You Failed" otherwise.

6. Program Execution (main())

• Calls ReadMark() to get user input.
• Calls PrintResults() to determine and display the result.
• Returns 0 to indicate successful execution.
