WebThe C++ Standard Library vector class is a class template for sequence containers. A vector stores elements of a given type in a linear arrangement, and allows fast random access to any element. A vector is the preferred container for a sequence when random-access performance is at a premium. WebSupport is also implemented for non-trivially copyable and move-only types, and alignment requirements are followed. This means that any type that can be stored in a vector can be stored in the static_vector and the program will work correctly. Rationale. For implementation, I relied on the C++14 standard template library for several reasons.
