Ok, here's the problem for the program that I have to do:

I'm supposed to make a program which inputs like 5students answers to a T/F Quiz....the program is supposed to match the # of correct answer inputted for each student with the answer key which is listed as 'TFFTFTTFTF' & output a grade such as 10 correct = 'A' , 9 correct = 'B' and so forth.....how would I go about starting this....what method do I use??? I need a response tonight, please help me!
