Why the pre-processor of C++ doesn't contain "<iostream.h>" header file?

Answer 1

iostream.h is header for C.
For C++ the header corresponding name is iostream ( without the ".h" extention )

Answer 2

iostream.h is mainly for C, although it is possible to use it for C++ , we only use iostream for C++. The reason why iostream.h isnt default for C++ is because it is slightly more limited and can cause bugs/errors, which is why we use iostream
