What is the difference between <iostream> and <iostream.h>

Answer 1

iostream.h is the old old way of referencing iostream. But using #include <iostream.h> is prestandard I believe (like before 1998)

Answer 2

iostream.h is pre-standard C++. It means that when you do a #include <iostream.h>, the preprocessor shall search for the iostream.h file and then includes it in your program

iostream is a standard header. It doesnt mean that it shall append a .h and then include iostream.h file. We used iostream.h before namespaces were introduced. So if you have a iostream.h file lying around, you can still include it. But it wont be in the std global namespace.
