Press me button game in c, download press-me-button game

Press me game in C:- In this game when you try to bring mouse near a button it moves away from the mouse, so you keep on trying pressing the button. In this game we have the coordinates of current position of mouse pointer at every moment of time, whenever we find mouse pointer very close to button we move the button suitably.
