Question

I have an array with x number of elements and want to print out three elements per line (with a for-loop).

Example:

123    343    3434
342    3455   13355
3444   534    2455

I guess i could use %, but I just can’t figure out how to do it.

Answer 1

For loop is more suitable:

var array = Enumerable.Range(0, 11).ToArray();
for (int i = 0; i < array.Length; i++)
{
    Console.Write("{0,-5}", array[i]);
    if (i % 3 == 2)
        Console.WriteLine();
}

Outputs:

0    1    2
3    4    5
6    7    8
9    10
