[Un]defined behavior

Object oriented programming focuses on bundling together the data with the operations that can be applied to them. Access specifiers allow you to control the invariants of the type, and deterministic destruction of objects provides the glue that makes...

As in the first post I wrote, less than a month ago, this time I am going to visit another stackoverflow question. The user has a template parametrized by a template argument and wants to write a non-templated function that takes an integer argument...

In the last post we discussed Named Return Value Optimization and one case of copy elision when constructing a variable from an rvalue expression.
But copy elision is not limited to those particular use cases. The question is where else can we take advantage of this optimization, and where the compiler will not be able to optimize away the extra copies....

C++ is a language with value semantics. It was designed so that user defined types will behave in the same ways that primitive types do. This offers advantages, but also imposes burdens on development: programmers have to implement those semantics, and...
