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 (ReadAge)

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

3. Range Validation Function (ValidateNumberInRange)

• Takes an integer number, lower bound (From), and upper bound (To) as input.
• Checks if the number is within the given range using:

return (Number >= From && Number <= To);

• Returns true if the number falls within the range, otherwise returns false.

4. Repeated Input Validation Function (ReadUntilAgeBetween)

• Uses a do-while loop to repeatedly prompt the user for input.
• Calls ReadAge() until the entered age falls within the valid range.
• Returns the validated age.

5. Output Function (PrintResult)

• Receives the validated age as a parameter.
• Prints "Your Age is: [Age]".

6. Program Execution (main())

• Calls ReadUntilAgeBetween(18, 45) to get validated age input.
• Calls PrintResult() to display the valid age.
• Returns 0 to indicate successful execution.
