You use the <iostream> header when you wish to make use of the standard input/output streams, which primarily includes std::cin, std:cout and std::cerr, amongst other standard IO stream facilities.
Note that C++ standard library headers do NOT have file extensions. That is, there is no <iostream.h> header in the C++ standard library. The only headers that do have extensions are those specifically provided by the C standard library. However, you must NOT include these headers in your own code as they will pollute the global namespace. If you require these headers, use the corresponding C++ header instead. For example, if you require <math.h>, include <cmath>. The C++ headers will import all the names from corresponding C header and place them in the C++ standard namespace.
