It seems that in C++ there is nothing easier than constructor and destructor. But some interesting things can make your life better if you keep them in mind when you write code.
In this talk we will discuss some of the tricks and pitfalls in coding, as well as broader topics, such as type design.
For example, what's the difference between a privately declared and a deleted constructor? (Spoiler: none.)
We will also discuss:
0/3/5 rules;
constexpr constructors;
explicit constructors and strong typing;
copy/move and equivalence;
destructors are now noexcept by default (and when destructors can still throw exceptions);
virtual destructors and polymorphism;
and few other things.
