ISO c++ or TC++PL

ISO c++ standard or "The c++ programming language by stroustrup"? and why?

[JLBorges]

Q: Why is the standard hard to read? I’m having trouble learning C++ from reading it.

The standard is not intended to teach how to use C++. Rather, it is an international treaty – a formal, legal, and sometimes mind-numbingly detailed technical document intended primarily for people writing C++ compilers and standard library implementations.

Fortunately, there are lots of good books that do teach how to use C++! See these recommendations as a starting point for high-quality tutorial and reference information about how to learn and use C++.

In this book, I aim for completeness. I describe every language feature and standard-library
component that a professional programmer is likely to need. For each, I provide:
• Rationale: What kinds of problems is it designed to help solve? What principles underlie
the design? What are the fundamental limitations?
• Specification: What is its definition? The level of detail is chosen for the expert programmer;
the aspiring language lawyer can follow the many references to the ISO standard.
• Examples: How can it be used well by itself and in combination with other features? What
are the key techniques and idioms? What are the implications for maintainability and performance?

Depends: are you writing a C++ compiler or are you using one?

The C++ Programming language is also a bit to digest. Its a great book, but I would say its a better second or third book than for someone new to the language. If you know the basics of the language and coding in general already, go for it.
