Multiple monitors and handles - c++

Question

Trying to run a for loop through physical monitors but the handles are really confusing me, I have pseudo code that runs along the lines of:
int tempCounter=0
for(counter = number of monitors;counter > 0;counter--){
RECT tempRECT;
HDC tempHDC;
Get resolution of DC handle (counter) -> tempRECT;
arrayList[tempCounter] = tempRECT;
Get virtual work area of DC handle (counter) -> tempRECT;
arrayList[tempCounter++] = tempRECT;
tempCounter++;
}
GetSystemMetrics(80) for the count of monitors, is this reliable enough to use, or any exceptions it might fail?
I know there is not much there, but looking on the MSDN just kept me going around in circles, that and I am not very competent at programming.

Answer 1

It can be as simple as this:
#include <Windows.h>
#include <stdio.h>
BOOL CALLBACK MonitorEnumProc(
HMONITOR hMonitor,
HDC hdcMonitor,
LPRECT lprcMonitor,
LPARAM dwData
)
{
printf("%dx%d\n", lprcMonitor->right, lprcMonitor->bottom);
}
int main(int argc, char*argv[]) {
EnumDisplayMonitors(NULL, NULL, MonitorEnumProc, 0);
}
