C# C# Nested Loops (Wtf!?)

[Mc Jayce 8]

So my c# teacher had to take a week off (to India, lolz), and as a result a random substitute teacher was given the task to teach a-bunch of beginners the Nested Loop. Which sucks and makes no sense!

Can anyone explain this to me in "simple person speak"?

*I know how loops work (for... while...) but this seems like LOOP-CEPTION

i.e.

for (blaablaa)

for (blaablaa)

-Good luck, and as always thank you!

Well this is a little late, but I'm answering anyway. The concept of having one loop in another is not that hard to understand.

For example, let's say we had 2 for loops (like you have), and we go like this:

for(int i = 0; i < 5; i++)
    for(int x = 0; x < 5; x++)
        Console.WriteLine("i: " + i.toString() + " | x: " + x.toString());

That would result in the output of:

i: 0 | x: 0
i: 0 | x: 1
i: 0 | x: 2
i: 0 | x: 3
i: 0 | x: 4
i: 1 | x: 0
i: 1 | x: 1
...

I don't see what you are having trouble with when looking at this. All you have to do is make sure that your variables in the for loop are different for every nested for loop, otherwise things will get screwed up. If you are still having trouble on this, mind elaborating on what is so confusing?
