Compares a for and a while loop that each generate the values 1, 2, 3, 4, 5.

Compare while and for Loops

Compares a for and a while loop that each generate the values 1, 2, 3, 4, 5.

The while loop uses a Boolean expression to determine when to end the loop:
The format of a while loop is:

while <Boolean expression>
{ <statements>

}

The examples below compares a for and a while Loop. Both examples generate the values 1, 2, 3, 4, 5.

	For Loop:		While Loop:
	for (int n = 1; n <10; n++) { listBox1.Items.Add(n); }		int n = 0; //initialize the variable while (n <10) { listBox1.Items.Add(n); n++; //increment the variable }

(One advantage of the while loop is that the Boolean expression can include AND and OR.)

Modify the program to generate powers of 2 using the code shown below:

//Programmer: Janet Joy
//While loop generates 1,2,4,8,...512
private void Form1_Load(object sender, EventArgs e)
{
   listBox1.Sorted = false;
   int n = 1; //initialize the variable
   while (n < 1000)
   {
      listBox1.Items.Add(n);
      n = n * 2; //increment the variable
   }
}
