Detecting Char Input
Hi,
I am currently writing a prog to show the use of exception handlers. Suppose you input a number such as: Code:
int a; cout << "Enter size of array: "; cin >> a; if (a < 0) throw "Size Must Be Positive!"; How can I detect if a entered was a character? I tried converting to ASCII but then suppose the user enters 400 as their input, then my ASCII code wont work. How can I detect if a character was entered so I can throw an error message before the prog crashes? Hope I explained myself. Thanks!

make "a" a character array, then use the atoi() function to convert whatever is entered into an integer value. That way if they enter a number, you get the actual number's value, but if you enter any characters, they are simply ignored....
