If you #include the <iostream> header into a C++ translation unit, the file will probably use the std::cin/std::cout/... global objects. However, C++ does not guarantee an order of initialization between static objects in different translation units, so if a static ctor/dtor in your .cpp file used std::cout, for example, the object would not necessarily -be automatically initialized before your use. -

To make std::cout and friends work correctly in these scenarios, the STL that we use declares a static object that gets created in every translation -unit that includes <iostream>.
