I posted this one before, ages ago, but it looks as if it has been cleared out, as the forum posts don't seem to go back that far.

Anyway, When I used Xwpe to compile Helloworld.cpp, I got a wordy warning about the library used, in this case iostream.h being depreciated.

I am using "Teach Yourself C++ in 21 Days", which is a few years old.

So, what libraries should I be using?

This warning means that you have used the declaration

The full warning is:

[GMorgan]

iostream is the central input and output header for C++, its crucial to most C++ programs. You could use cstdio or stdio.h* but that is orignal C rather than C++. Your using Ubuntu aren't you, have you tried sudo apt-get install build-essential, it should ensure that your uptodate with the libraries.

*the original C headers used the .h notation. In C++ they dropped the .h. C++ also included original C functions repacked for C++ but with c in front of the original name. Hence stdio.h becomes cstdio, they both perform the same functions. iostream should work though and is the standard way of doing things in C++.

What warning did you get when you used the <iostream> declaration?
