Right before deciding that you cannot pay for or don’t like exception-primarily based mistake dealing with, Possess a consider the choices;
Regardless if other containers appear a lot more suited, this kind of map for O(log N) lookup performance or a list for efficient insertion in the middle, a vector will usually nevertheless execute greater for containers up to a couple KB in dimension.
For those who determine a destructor, you shouldn't utilize the compiler-created copy or shift Procedure; you probably have to determine or suppress copy and/or shift.
Corollary: When composing a base course, often create a destructor explicitly, because the implicitly created a single is community and nonvirtual.
