It used the basic controls like buttons.When you start the program, you can see nineteen buttons and textfile on the top of the window. There are different words on the buttons such as “o”.Once you clicked one button, a result would be show on the textfile. If you clicked the “1” button, 1 would appear,then you clicked the “+” button, then you clicked the “2”button,2would applear,then you click the “=”button,3 would applear,and so on. Finishing this project, we can learn how to build anapplication in VC+, how to use the basic controls and how to deal with the mouse events.Screen shot1.
