Why iostream.h is not valid, and how to use it if I want to make programs by old c++

Answer 1

Actually, it used before 2002. But after 2002 c++ community and bell lab change it and remove .h from header file. From there this is the standard of c++. When you write iostream it simply means you are calling a header file. Now all compiler shows this as a standard of c++. If you get a compiler which is before 2002, and not been updated since than. You can use it. But Why you want that, bell lab done this for user benifit.
