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. Function (PrintLettersAtoZ)

• Uses a for loop to iterate through ASCII values 65 to 90, which correspond to:
  • 65 → 'A'
  • 66 → 'B'
  • ...
  • 90 → 'Z'
• Converts each ASCII value to its corresponding character using char(i).
• Prints each letter on a new line.

3. Program Execution (main())

• Calls PrintLettersAtoZ() to print letters 'A' to 'Z'.
• Returns 0 to indicate successful execution.
