Mike, have you done your studying? code is rather easy.. check out dreamincode.net.. Btw.. try using a case statement. MUCH easier.

wtf

its been a while... i only remember printf and scanf and arrays...

I believe thats Java statements

im not quite sure what the goal is for your program.. do you want the user to just input 1 grade or more than one?

if more than one, you need your program to gather all user data.. and this is where its tricky b/c im sure if you are assuming all grades are out of 100. Explain to me exactly what your program needs to do so I can further assist you.



let me know the goal
