如何让我的程序在屏幕上出现和消失

Question

My program simulates some mouse movements, but the cmd screen remains open, I would like to put a key to appear and disappear from the screen, and another key for it to close completely

Answer 1

If "cmd screen" is meant as Windows console then there are simple Windows API calls:

// this hides console window
::ShowWindow(::GetConsoleWindow(), SW_HIDE);

// this shows
::ShowWindow(::GetConsoleWindow(), SW_SHOW);

// this checks visibility
if (::IsWindowVisible(::GetConsoleWindow())) {
    // do your things
}

You need to include windows.h for those. As you wrote that you alter mouse you have likely done it already.
