Method one, using the GetSystemMetrics function

The GetSystemMetrics function is prototyped as follows:

int WINAPI getsystemmetrics (  __in  int nIndex);

Each desired information corresponds to an index value, and the index value is passed as a parameter to the getsystemmetrics, and the corresponding information is obtained. where Sm_cxscreen and Sm_cyscreen respectively correspond to the width and height of the screen, in pixels.

int widescreen=int highscreen=if (widescreen==0| | highscreen==0) {      printf ("cannot get the resolution!\n");}   Else {      printf ("Thescreenresolution is  %dx%d", Widescreen, Highscreen); }
