If I can get the teacher to accept this error free, I might just make a B

you dont need float median-float maximum-float minimum

i fixed for you hope it helps

i tryied to remove comments but took to long...

Uninitialized variable means that you are using a variable that has no set value. Initialize all of your variables to zero or some other value before you use them. (Unless there is input that initializes them)

Also that code is error free, those are just warnings.
