WHat is your input?

Are you sure it reads the value that you are expecting? Print the value of grade on line 6 to make sure.

Note that get() reads unformatted input. It does not ignore whitespace characters.

the problem was that everytime after I input a character and pressed enter a newline was entered too which was filtered by default label. I solved this by making a special case for the newline case '\n': break;

why not use formatted input instead?
