Array sum Need Help

[CodeMonkeyJunk]

I have a school project and what is needed is to Write a program that prompts the instructor to enter the 10 grades of midterm 1 and store these numbers in an array. Next prompt for the 10 grades of midterm 2 and store these numbers in a different array. Next prompt for the 10 grades of the Final Exam and store these in a different array. Next add midterm1 to midterm2 to Final and store the totals in a different array. Next, scan the array that has the totals and identify the minimum grade and maximum grade. Inform the instructor of the minimum grade and maximum grade.

The problem is i cannot get the min to work right. Right now just using 3 array indexes when this gets working then i will use the 10.

Thanks for the Help.

>>int min = total [0];

there's not gonna be a value less than 0
why don't you set min as the first value of the array after the array is filled

Okay thanks Zeroliken for the input it cleared up my over thinking.

here is the completed code just for anyone to reference.
