#1: Create a windows application that has the functionality of a calculator and works with integral values. Allow the user to select buttons representing numeric values. If the user attempts to divide by zero, throw and handle an exception.
#2: Create a windows application that has the functionality of a calculator but works with decimal values. because division by zero is not thrown by the CLR when the operands are nonintegral, create a custom exception class that can be thrown if division by zero is attempted. instead of doing the division, display a message indication that division by zero is not possible.
