Calling AccessInvalidArrayElement()
Attempting to access an invalid array element
Handling an IndexOutOfRangeException
Message = Index was outside the bounds of the array.
StackTrace =    at MainClass.AccessInvalidArrayElement()
Calling DivideByZero()
Attempting division by zero
Handling an IndexOutOfRangeException
Message = Attempted to divide by zero.
StackTrace =    at MainClass.Main()
