Hi. I am goodn. i hope to contribute helpfully to your board later, but right now I am the one in need of help. In my c class we are starting to go over Arrays. I really have no grasp of them, other than knowing

int[5] = {4, 6, 7, 2, -1}

is an array of size 5 with values 4, 6, 7, 2, and negative 1. I don't understand their application into programming at all. The way I tend to learn things is by seeing an example, but my prof. doesn't supply any.

Anyway, an assignment I have is to make a tone of functions in a header file using arrays such as isum, dsum, iaverage, daverage, imin, imax, dmin, dmax, etc.

I think if I could get a push in the right direction I would easily be able to do this. If someone could be so kind as to show me how one would do

Code:
isum
This function will take an integer array of numbers and the array size as its parameters. 
It will return the sum of all the numbers in the array as an integer.
then I think I could do the rest no problem. I've already done very similar functions without arrays, so if someone could give me a start, I'm sure I could do the rest with arrays. I'll post my progress back here. Thanks.
