==Compute integer powers of 2 with while loop==

<source lang="csharp">using System;

class MainClass {
public static void Main() {
int e;
int result;

for(int i=0; i < 10; i++) {
result = 1;
e = i;

while(e > 0) {
result *= 2;
e--;
}

Console.WriteLine("2 to the " + i + " power is " + result);
}
}
}</source>
<pre class=codeResult>2 to the 0 power is 1
2 to the 1 power is 2
2 to the 2 power is 4
2 to the 3 power is 8
2 to the 4 power is 16
2 to the 5 power is 32
2 to the 6 power is 64
2 to the 7 power is 128
2 to the 8 power is 256
2 to the 9 power is 512</pre>

==Simplest While loop==

<p>The general form of the while loop is</p>

<source lang="csharp">while(condition) statement;</source>

==Use a while loop to calculate and display the Fibonacci numbers less than 50==

<source lang="csharp">class MainClass
{
public static void Main()
{
int oldNumber = 1;
int currentNumber = 1;
int nextNumber;
System.Console.Write(currentNumber + " ");
while (currentNumber < 50)
{
System.Console.Write(currentNumber + " ");
nextNumber = currentNumber + oldNumber;
oldNumber = currentNumber;
currentNumber = nextNumber;
}
}
}</source>
<pre class=codeResult>1 1 2 3 5 8 13 21 34</pre>

==Use a while loop to display 1 to 5==

<source lang="csharp">class MainClass
{
public static void Main()
{
int counter = 1;
while (counter <= 5)
{
System.Console.WriteLine("counter = " + counter);
counter++;
}
}
}</source>
<pre class=codeResult>counter = 1
counter = 2
counter = 3
counter = 4
counter = 5</pre>

==Use count number to control while loop==

<source lang="csharp">using System;

class MainClass {
public static void Main() {
int num;
int mag;

num = 435679;
mag = 0;

Console.WriteLine("Number: " + num);

while(num > 0) {
mag++;
num = num / 10;
};

Console.WriteLine("Magnitude: " + mag);
}
}</source>
<pre class=codeResult>Number: 435679
Magnitude: 6</pre>
