WebThe C++ function std::vector::resize () changes the size of vector. If n is smaller than current size then extra elements are destroyed. If n is greater than current container size then new elements are inserted at the end of vector. If val is specified then new elements are initialed with val. Declaration 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. Syntax greenwich delivery number pasig
