ack, n/m

++++++++++++++++++
here's my $.02. it's still the same, but made small changes so it works on my compiler and because i was bored. i only made 3 instead of 5 because of lack of time during the time when i was coding this, so if you want to add 2 more, go for it... just don't forget to edit in 3 areas, prototypes, main, void functions...

also added a lil function that reports a letter grade to the average given.

peace.
