Answer 3

Vector in C++ STL. Vectors are same as dynamic arrays with the ability to resize itself automatically when an element is inserted or deleted, with their storage being handled automatically by the container. Vector elements are placed in contiguous storage so that they can be accessed and traversed using iterators
ectors in C++ C++ has a vector class within the std namespace. A vector is similar to an array, in a sense where a series of elements are stored with the same variable name. Unlike arrays, vectors are dynamically sized, which is a major advantage.
