C# Lesson 6

The while statement is simple loop. As long as the condition inside the while() evaluates to true, the section of code will keep repeating itself.
Afterwards you can continue to the next lesson!
Or go back and review the previous lesson.
We also have the source code on GitHub.

    class WhileLoops
    {
        static void Main(string[] args)
        {
            //if (true)
            //{

            //}

            //while (true)
            //{
            //    Console.WriteLine("The WHILE is true");
            //}


            //int numberOfLoops = 10;

            //while (numberOfLoops > 0)
            //{
            //    Console.WriteLine("numberOfLoops = " + numberOfLoops);
            //    numberOfLoops = numberOfLoops - 1;

                userInput = Console.ReadLine();

                if (userInput == "1")
                {
                    Console.WriteLine("Moo");
                }

                {
                    Console.WriteLine("Meow");

/*
* TASK:
*   Make a while loop that prints 10-20.
*   Print '**********' to the console.
*   Make a while loop that prints all the even numbers from 2 - 20
*   Print '**********' to the console.
*   Make a while loop that prints the powers of 2 from 1 - 256
*   
*   Example output:
*       10
*       11
*       12
*       13
*       14
*       15
*       16
*       17
*       18
*       19
*       20
*       **********
*       2
*       4
*       6
*       8
*       10
*       12
*       14
*       16
*       18

*       32
*       64
*       128
*       256
*   
*   BONUS POINTS:
*   Research how to use Console.Write() and use it to print the output on a single line each
*   with spaces between the numbers.
*   
*   Example Output:
*       10 11 12 13 14 15 16 17 18 19 20
*       **********
*       2 4 6 8 10 12 14 16 18 20
