    Average in arrays

    How do you find an average of each row in a 2-dimensional array and make the last column hold the average?
    Thanks

    Here's a tip - try your assignments rather than just dumping them all on the board.
    reversing integers
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    It wasn't an assignment I'm trying to study and going through things I'm not sur about. I was asking for help as that is what this whole web site is about. Don't assume anything about me or why I'm asking for help. Also don't answer me if you've got noting helpful to say. Just ignore it if you don't want to answer.... obviously you have way too much time on your hands!!!

    Then how about you read this announcement:

    And the couple of others there simply to enhance your prospect of a response. Otherwise you will be treated like a leech.

    7. It is easier to write an incorrect program than understand a correct one.

    As I Said It's Not Homework It Is Study!!!! This Isn't A Program That I Have To Do And Hand In.

    And obviously you have little since you didn't even provide us with some code that at least showed you made an effort to answer your own question. Any assesment that you are a lazy person is thus quiet... normal.

    Calm down. You type too many exclamation marks. Move that anger towards solving this array problem of yours. That's the one bugging you. If you do just that you will get answers when you next come and ask why your code isn't working. Other than that... good luck

    Ah... alright you are right. Sorry
    You don't deserve this. Ok... so, how to find the average on that 2D array...

    An average of any given array of numbers is equal to the sum of its element values divided by the number of elements in the array.

    Homework, either personal or for school, is still homework.

    Try a new thread that posts your attempt, or PM a mod to reopen this.
