STL implementations

  • libstdc++ GNU's C++ STL implementation.

  • libc++ Clang's C++ STL implementation.

  • hackingcpp Articles, Cheat Sheets and tutorials for modern C++ and standard library features.

  • cppreference Reference for entire C++ std library

  • C++ Core Guidelines C++ core guidelines maintained by Bjarne Stroustrup and Herb Sutter.

  • cppexamples Examples of various c++ idioms, patterns, and STL functionality.

Books

I've read a ton of books on C++, these are the books which I find to be both excellent and (more or less) up to date with modern C++.

  • The C++ Programming Language A very thorough guide/reference of modern C++, which covers most of the language. I really like this book!

  • C++ Templates - The Complete Guide Solid reference for template metaprogramming. The next step after this book is usually to look at STL implementations.

  • C++ Concurrency in Action Great book covering C++ standard library concurrency and parallel computing. If you're interested in OpenMP, MPI or other resources on parallel or distributed programming I suggest you look at my recommended resources on my computing page

Object Size and sizeof

The size of a an object of type T can be found by using the operator sizeof(T). It's a constant expression which resturns the number of bytes of T as asize_t. A byte is at least 8 bits, but may be larger (architecture-dependent) and the number of bits per byte is stored in the macro CHAR_BIT defined in the <climits> header.

Object Alignment, alignof and alignas

template<typaname T>
void print_class() {
    std::cout << "The size of class: " << typeid(T).name() << "is: " << sizeof(T) << " bytes\n"
}

Checking if a pointer points to memory inside a region

Comparing pointer's can be tricky. There is good blog post which show the intriciacies of pointer comparisons and memory regions by Raymon Chen: * How to check if a pointer is in a range of memory

In C++ there i s a nice solution to the problem, using function objects from the <functional> header. The std::less and std::greater function objects are guaranteed produce a strict total order for pointer types T* even if the < operator does not (see e.g. std::less cppreference and the pages for the other functional comparison operators).
