Declare a double variable before the loop. During loop sum all marks to this variable. After divide the sum(variable) by 5 or by the array's length if you plan to add more elements.

As a side note, it might be better to use a floating point type for the <student_marks> field. Use of int for average isn't really a good idea, because average is supposedly a percentage value : )
