Question

Using C#: Create a Form that consists of 4 checkboxes, three radio buttons, a label and a button. The 4 checkboxes represent pizza toppings. The three radiobuttons should represent three sizes of pizza, namely “small”, “medium” and “large”. When the user clicks the button you need to calculate the price of the pizza. The calculation should be done as follows: count up the cost of the selected ingredients (you may assign your own prices for the ingredients) and then multiply this cost with 1 for a medium, 0.5 for a small and 2 for a large. Display the calculated price in the label.
