This example is designed to ask you to clean the screen by clicking mouse. Use Visual Studio to create a C++ Console App to run it. In the code, the following line must be included: \#define KEY_DOWN(VK_NONAME) ((GetAsynaKKeyState_(VK_NONAME) \& 0x8000) ? 1:0) In addition, VK_LBUTTON, VK_RBUTTON, VK_MBUTTON indicate left button, Right button, Middle button respectively. //Example \#include \#include > \#define KEY_DOWN(VK_NONAME) ((GetAsyncKeyState_VK_NONAME) \& 0x8000) ? 1:0) //Must have this line using namespace std: int maing while (1) \} printf("Hello World! ONLY RIGHT CLICK TO CLEAN THE SCREEN.|n"2): if (KEY_DOWN(NK_LBUTTON)) \{ 3 if (KEY_DOWN(VK_RBUTTON)) \{ printf("Right click to clean the screen. Pause 1 second."): Sleen(1000);//pause 1 second system("cls")://Clean the screen \} if (KEY_DOWN(VK_MBUTTON)) \{ system("pause")://pause \} Sleen(20); //set time interval. \} return 0 a. Run the code and insert the screenshot below. b. How the function Sleep(1000) works? c. Please try to design a new feature and modify the code, e.g., change the background color or font color.
