#include <iostream> is a compulsion to use as it is a header file without which your program execution will be incomplete. actually iostream stands for input output stream which signifies the use of cin & cout in the program.

I understood your question as: why not use the declarations from stdio.h instead of iostream? iostream is the C++ stream library header, which declares the C++ way of dealing with (text) IO. stdio.h is the header that provides the C-style function declarations. Trying to write readable, proper C++ code you should use iostream. Nevertheless, the functions from stdio.h are sometimes a bit faster... Therefore, as long as, say, 10% IO performance are not relevant, include iostream, otherwise include stdio.h.
