Part 3 of Bjarne Stroustrup's draft Tour of C++ is now available. This material is a preview draft of Chapter 4 of Stroustrup's upcoming The C++ Programming Language, 4th Edition.

Stroustrup writes:

No significant program is written in just a bare programming language,

it would be too tedious.

However, just about any task can be rendered simple by the use of good libraries.

This third chapter of my tour of C++ begins the presentation of the standard library, which is about half of the C++ standard.

Constructive comments would be most welcome.
