I need to write numbers from 0-100 on the console, like this:
0,1,2
1,2,3
2,3,4
3,4,5
etc.
I really can't seem to figure this out. Any pointers would be nice!

2Have you tried using a simple (optionally nested) for loop? – the default. Apr 04 '19 at 12:44

2Think about it this way. You want to print that middle number on each line from 1-99. Then you just subtract one to the the first number and add one to get the last number for each line. – juharr Apr 04 '19 at 12:46

sounds like a very, very basic task ;) – Esteban P. Apr 04 '19 at 12:46

You need to iterate through all integers from 0 to 100 and output i, i+1 and i+2 on each line. The previous sentence is 90% complete code, just translate it into C# :) – Yeldar Kurmangaliyev Apr 04 '19 at 12:47

@someone Yeah I tried a while loop, but couldn't crack the code for having 3 numbers on 1 line. – Johan Johannesen Apr 04 '19 at 19:15

@EstebanP yeah, I know it is and I've tried a couple of things, just can't crack it. Just starting out. – Johan Johannesen Apr 04 '19 at 19:27

@YeldarKurmangaliyev that was exactly the way I was thinking of doing it! I jsut can't seem to do it. – Johan Johannesen Apr 04 '19 at 19:28

It's quite easy actually, something like:
for(int i = 0; i < 100; i++) {
Console.WriteLine(string.Format("{0},{1},{2}", i, i+1, i+2));
}
It will goes from 0 to 101 because it always prints 3 numbers so the last iteration would be 99,100 otherwise. If you want it that way just edit i < 100 with i < 99.

A LINQ way of achieving it:
Enumerable.Range(2, 99).ToList()
.ForEach(x => Console.WriteLine($"{x - 2},{x - 1},{x}"));
