GetExitCodeThread(HANDLE, LPDWORD exit_code) tells you the exit code of the
thread. exit_code is STILL_ACTIVE if the thread is running, the actual exit
code if it has completed. For example,

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

DWORD WINAPI ThreadProc(LPVOID );

int main()
{
  for(int i = 0;i<3;i++)
  {
    DWORD threadId;
    DWORD exit_code;
    HANDLE hThread;

    hThread = CreateThread(NULL,0,ThreadProc,&i,0,&threadId);
    if(hThread == NULL)
      cout << "\n Thread has not been created";
    else
    {
      //_getch();
      cout << "\n Thread has been created successfully.";
      
      do
      {
        GetExitCodeThread(hThread, &exit_code);
      } while(exit_code == STILL_ACTIVE);
      cout << "\n Thread " << i+1 << " has completed.\n";
    }
  }
  return 0;
}

DWORD WINAPI ThreadProc( LPVOID lpParam )
{
  cout << "\n Entered threadProc...";
  MessageBox(NULL,"sample output","",MB_OK);

  for(int i = 0;i<10;i++)
  {
    cout << "\n thread output is:"<<HIWORD(lpParam) << ".."<<i;
  }

  return 0;
}
