How to make a c++ program physically press a key?

Question

Now, i've been trying to make a C++ program that physically presses the D or A key, I am still a beginner in C++ and most recent thing i've learned is while loops. Thanks for anyone that could help :)

I want to do this because in a game I play, you go idle then you get kicked out for being idle. Thats why I'm trying to do this.

You want to simulate a keypress? Because *physically* pressing a key requires something... well, *physical*. — Borgleader, Jan 03 '15 at 23:18
C++ doesn't have a way to do this, you'll have to look at the API for your platform. — MrEricSir, Jan 03 '15 at 23:18
I don't know, but it sounds like OP wants to send a signal to the game that a key was pressed repeatedly to prevent idle kicks. Sounds tricky. — D. Ben Knoble, Jan 03 '15 at 23:22
Is this on microsoft windows? If so one way is to send window messages to the window that you want to receive the keypress. — drescherjm, Jan 03 '15 at 23:26

For Windows, I think this is achievable using the SendInput function to inject key presses into the target application.

You can find the API documentation here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms646310%28v=vs.85%29.aspx

See how to use sendinput function C++ for an explanation and a complete example of its use.
