Iostream Objects' Memory Use

 
#include 
#include 

using namespace std ;

void main()
{
  _CrtDumpMemoryLeaks( );
}

Answer:
_CrtDumpMemoryLeaks( ) lies. The iostream objects are constructed before main() starts and they are destructed after main() exits. Therefore, _CrtDumpMemoryLeaks() thinks that there's a memory leak, because the memory isn't released when by the time main() exits. Instead, it is released afterwards, during the destruction of the iostream objects.
