# include<iostream.h>

  • Istream class supports Input function.
  • Ostream class supports output function.

            All objects are included in iostream file So, we can use input or output statement in our programs.

using namespace std;
  • It includes all C++ standard libraries.
  • We do not use this in old IDE like Turbo C++ but we have to use this in all new IDE like Code Blocks, Dev C++ etc.
