Print a box, which can be moved freely in the plane and control a coordinate point in the box so that it cannot be moved outside the box.

Print a box, which can be moved freely in the plane and control a coordinate point in the box so that it cannot be moved outside the box.

Development Environment: ubuntu 12.04
Development tools: gcc compiler, vim Editor

Function:

Print a box that can be moved freely in the plane. You need to control a coordinate point in the box so that it cannot be moved out of the box.

Purpose:

It can be used for technical training.
