he new C++09 nullptr keyword designates an rvalue constant that serves as a universal null pointer literal, replacing the buggy and weakly-typed literal 0 and the infamous NULL macro. nullptr
opy construction, assignment, container reallocation, string concatenation, and string copying are all instances of copy operations. However, in recent years a new paradigm is emerging: move semantics. This discussion presents
++98 has two native character types: char and wchar_t. The latter is purportedly used for manipulating Unicode strings. In reality however, wchar_t is unsuitable for this purpose. The C++09 standard
A month ago, I discussed the strfmt() function. A timely announcement from Microsoft has inspired me to write a column about a related topic, namely accessing the system’s Daylight Saving
any moons ago, I presented C++’s basic time and date facilities. At that time, however, I didn’t demonstrate how to format and customize the date and time. Such customizations may
num types have been a valuable asset in the arsenal of C++ programmers for many years. However, their current specification has some security loopholes that can lead to bugs and
onstant expressions are tricky. Not all of them have an overt const qualifier. Furthermore, in some cases, a const-qualified variable is just a constant, but not a constant expression. These
Many object-oriented programming languages allow a constructor to delegate its object initialization to another constructor of the same class. But in C++98, this isn’t permitted. Consequently, a C++ class with
R1 recently enhanced the standard header with a small reference wrapping library that includes the class template reference_wrapper and the helper functions ref() and cref(). This mini-library library solves the
