HelpNeed Information About Mouse Clicking

Hello

I need help on how to make a clicking 1,2,3,4,5.
My sleep will be 100.

I think use a loop
double n= 999999999999;
for (int e=1; e<n; e++) { here clicker with sleep }

And i think to make a start program for P and a stop for O.

I want to do in a normal project, no d3d

Im learing dev c++ from school because we take only program's a type calculator.

Because i write here to get more information about that code.

Thanks You

#include <windows.h>
#include <iostream>

using namespace std;

int main()
{
cout << "Clicking...";
while(true)
{
mouse_event(MOUSEEVENTF_LEFTDOWN,x,y,0,0);
mouse_event(MOUSEEVENTF_LEFTUP,x,y,0,0);
}
return 0;
}

Are you trying to see if the ASCII value is returned and process it with an if statement or are you trying to send a mouse click?
