Hi,
I've been trying to figure out how to compare two strings and to output the amount of letters match and don't match and display which ones those were, like in an answer key.
Say, there is a True/False test written by a student and the answer key is FTFF. He writes FTTT. Therefore he will get 50%, and questions three and four were wrong.
How do you go about this? Maybe I'm missing something blatantly obvious but I can't figure it out. Maybe I'm not supposed to use strings? Anyone got an answer?
