C ++新手：我需要帮助来创建一个简单的计时器函数

Question

I'm a C++ beginner. I'm searching for a way to may a simple timer function for a very simple console game (class assignment). Hopefully a preexisting function from a common library? Please keep it simple since I am new. Thanks. Sorry if I'm not wording this correctly. Brand new to this forum as well!

It's not that different from any other loop or iteration, simply use the given values/constant as your condition.

Answer 2

you can use the time function from #include <time.h> . Use it to get a start and stop time, then subtract to get the elapsed time. Info here .

Answer 3

Assuming you are using plain C++ in Win32 there is a function SetTimer() from the Win32 API that goes like this

UINT myTimer = SetTimer ( hwnd, ID_60SECONDS, 60 * 1000, NULL );

You will then need to add a case statement to your WndProc to handle the elapsed timer

case WM_TIMER:
switch (wParam)

{

    case ID_60SECONDS:

    // We processed it, so return 0

    return 0;

}

break;

Unfortunately, this involves dealing with Win32 which is no that easy but once you got the hang it is very obvious.

I took the code from this tutorial.
