iostream.h is not part of ISO C++. The name was changed to <iostream>
    (no suffix) during the standarization process which was completed
    in 1998. (Although the iostream.h => iostream change was final
    long before most of the other changes.)

Since you don't know about <iostream>, I'm going to assume you don't
    know about the std namespace. During the standarization process,
    all standard C++ library names, including cout, endl, string, etc,
    were moved into the std namespace. Here is an example:

#include<iostream>
#include<ostream>

using std::cout;
using std::endl;

int main()
{
    cout << "Hello world" << endl;
}

I think there is some confusion. If iostream is required, but not
    found, the program will not compile. You must copy and paste the
    exact error messages you get, and the code that reproduces them
    (or a simplified version thereof). If you don't do that, people
    can only guess at your problem, and are less able to help you.
