Operation

The user enters a numerical grade from 0 to 100 and clicks the Convert button or presses the Enter key to activate that button.

Specifications

The grading criteria follow:

A 90-100 B 80-89 C 65-79 D 50-64 F

Assume that the user will enter a valid integer for the grades so your code doesnt have to check this entry for validity.

Code the application using the IfThenElse statement.

Show an error message if the grade entered is out of range (less than zero or greater than 100).
