You have to include windows.h header. Here is an working example.

#include <stdio.h>
#include <windows.h>
#include <winuser.h>

int main() {

    DEVMODE devmode;
    devmode.dmPelsWidth = 1024;
    devmode.dmPelsHeight = 768;
    devmode.dmFields = DM_PELSWIDTH | DM_PELSHEIGHT;
    devmode.dmSize = sizeof(DEVMODE);

    long result = ChangeDisplaySettings(&devmode, 0);

    return 0;
}
