#12 – C# while loop

The while statement executes a statement or a block of statements while a specified Boolean expression evaluates to true, a while loop executes zero or more times.

using System;

int i = 0;

while (i < 100)
{
    int j = i;

    while (j < i + 10)
    {
        Console.Write($" {j} ");

        j++;
    }

    Console.WriteLine();

    i += 10;
}

Output:

 0  1  2  3  4  5  6  7  8  9
