Question [SOLVED] Is there a function or method to ignore elements within an array?

    Project: Fantasy RPG - Character Creation - Stat System

    I have an array: int[] that stores additional stats in each element based on a player class selection.
    These points are added to base stats that derive from a race selection.
    The class selection stats are added together for a total sum.
    I have a separate int of 50 called bonus points.
    The sum of the class selection stats are subtracted from 50 for a final total that players can then distribute to their stat tree.

    The problem I am running into is that there are some elements in the array I would like for this sum calculation to ignore, and only add together the basic stats (elements 0 through 6) and ignore the resistance stats (elements 7 through 12).

    Short of splitting the stats into two arrays and coding around this, is there any way to ignore these elements in the array?

    My current solution is a bit of an array hack. (See attached images)
    I lock the array to 14 elements, then add 7 elements at the start of the array to "push" the elements I don't want calculated out, and it retains the ones I want kept in - but this just feels like a dirty fix that could produce bugs later - and because this is a character creator, I need to be sure to pass the correct information forward before the character is stored into save data.

    The continue keyword can be used to move onto the next enumeration of a loop:

    That said:
    Then just write a for-loop that only enumerates the first 7 elements? I feel like you've missed the most obvious solution here.

    It also might be worthwhile using a more meaningful data type than just an integer. A wrapper class that can express additional information would probably be more useful.

    Well yes, the obvious solution is the one I was seeking lol - I know what I wanna do, just didn't have the syntax for it. "Enumerate" was the key word in this, I think.
    I'm still really new to coding, I only started a week or so ago.
    Googling "enumerate elements in an array" got me some results - so this was helpful. Thanks.
    I've considered converting to Dictionary, or List from Array, but I need to study more on those.

    Going to try Linq.Take()

    Well you could use .Take(), but in all cases you'll enumerate over the result it gives you, so why not enumerate over the first n elements of your array directly, and avoid one useless operation (.Take) :

    Code (CSharp):
    1. // Enumerate over the first 7 elements in your array
    2. // Just make sure your array has at least 7 elements
    3. // or else you'll get an IndexOutOfBounds exception
    4. for (var i = 0; i < 7; i++)
    5. {
    6.     var item = yourArray[i];
    8.     // work with the item...
    9. }
