My friend and I have almost finished the Magic Square Program. All that is left is have the program check to see if the user inputted a Letter instead of a number. (i.e. "Input square: g") after g has been inputted into the program instead of a number 1-9, the program will just keep displaying the same phrase over and over and keep repeating until you physically exit the program. Is there any way using the "isalpha" function and incorporate it into the program and have the program display the if it is a letter that was inputted. Any help will be appriciated.
