what do you think about this?
It is a good way for threads?

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

unsigned count=0;
unsigned index=-1;
unsigned array[256];

#define ini InitializeCriticalSection
#define lock EnterCriticalSection
#define unlock LeaveCriticalSection
#define end DeleteCriticalSection
#define P printf

CRITICAL_SECTION dataTh;

int hhh;

unsigned long __stdcall PrintMsg(void* a)
{//thread function
 unsigned aa;

 aa=*(unsigned*)a;
  while(count<=100)
  {lock( &dataTh );
   count++;
   if(count<=100)
      {cout << "Tread number=" << aa << "; ";
       cout << "I Incremented count: " << count << "\n";
      }
   else {++hhh; P("wait 10sec hhh=%d\r", hhh);}
   unlock( &dataTh );
  }

 return 0;
}

unsigned StartMe(int i)
{// starting thread
 unsigned long id=0;
 void *hThread;

 ++index; index&=255; array[index]=i;
 hThread=CreateThread(0, 0, PrintMsg, array+index, 0, &id);
 if(hThread == 0 ) return -1;
 return 0;
}

int main(void)
{int i;

 ini(&dataTh);

 for(i=0; i<100; ++i)
       if((int)StartMe(i)==-1) break;

 Sleep(10000); // 10 secondi

 end(&dataTh);
 printf("\n");
 return 0;
}
