Lesson 37STL Basic Concepts

Stl

Vectors (vector) belong to a sequence container that accommodates indefinite long line sequences, providing fast random access to sequences (also known as direct access)

A vector is a dynamic structure that simulates a dynamic array, which is not fixed in size and can be increased or decreased while the program is running.

The elements of a vector can be of any type T, but must have assignment and copy capabilities, copy constructors with public and overloaded assignment operators

Lesson 38vector

Stl

The size of the vectors (size) and the capacity (capacity) are usually different, capacity returns the number of elements the vector actually can hold. If more than this amount requires reconfiguration of internal storage
