Generating keystroke using Linux OS

[A'mirul]

Hi guys, I need help in doing what this code do but in Linux. Basically its a code to create keystroke about 5 seconds after the code is running. Below are the code in c++. Thanks on advance.

int main()
{
    // This structure will be used to create the keyboard
    // input event.
    INPUT ip;

    // Pause for 5 seconds.
    Sleep(5000);

    // Set up a generic keyboard event.
    ip.type = INPUT_KEYBOARD;
    ip.ki.wScan = 0; // hardware scan code for key
    ip.ki.time = 0;
    ip.ki.dwExtraInfo = 0;

    // Press the "A" key
    ip.ki.wVk = 0x41; // virtual-key code for the "a" key
    ip.ki.dwFlags = 0; // 0 for key press
    SendInput(1, &ip, sizeof(INPUT));

    // Release the "A" key
    ip.ki.dwFlags = KEYEVENTF_KEYUP; // KEYEVENTF_KEYUP for key release
    SendInput(1, &ip, sizeof(INPUT));

    // Exit normally
    return 0;
}

I'm going to write this is a well done question. But the search I used lead me to a Python solution that covers Windows, Linux and Mac OS at https://automatetheboringstuff.com/chapter18/

Also https://www.google.com/search?q=Generating+keystroke+using+Linux+OS&gl=US finds priors so to me this looks to be well done.
