6.3 For-loop through a List

1. Remove the line ShowInformation(myCircles[1]); from your Main method.

2. Add the following code to your Main method:

   for (int i = 0; i < myCircles.Count; i++)
   {
       ShowInformation(myCircles[i]);
       Console.WriteLine();
   }
   

   • Always start your for-loop with 0.
   • The index must never equal Count. Count = 2 means indices 0 and 1 are valid!

3. Run your program. You will see the information about the two circles present.

4. Remove the code above and add the following code:

   foreach (Circle circle in myCircles)
   {
       ShowInformation(circle);
       Console.WriteLine();
   }
   

   circle is the variable name of type Circle that iterates through the myCircles list.

5. Run your program. Your output is exactly the same as above.
