Arent the comments clear enough to make so that you can yourself do the documentation ?

sorry i sent the wrong code..anyways can u help me...can u tell me another way of solvin this problem...this program allows input of number of students,marks for each student,the frequency for each mark, the interval between identical marks...

if you posted the wrong code then you need to post the correct code. We don't care if the code you posted doesn't work. Post the code you know how to do then we can talk about how to complete the assignment.

by "mark" do you mean "grade" ?

>>the interval between identical marks
what exactly does that mean?
