Answer:
If the user types in "A" as an input, the program will raise a ValueError exception, because the input "A" is not a valid integer. The int() function is used to convert a string representation of a number to an integer, and it raises a ValueError if the input string cannot be converted to an integer.
The error message will be: "invalid literal for int() with base 10: 'A'"
And the program will stop executing. To avoid this, you can use try-except block to catch the exception and handle it by providing a proper error message or any other action you want to take.
