vector Vectors are sequence containers that represent arrays that can be resized. Like arrays, vectors use contiguous storage locations for their elements, which means that their elements can also be accessed using offsets on regular pointers to their elements and are as efficient as arrays. But unlike arrays, their size can change dynamically, ...

Reproduced in: Several ways of deleting elements in C++ STL vector (super detailed) (biancheng.net) As mentioned earlier, whether you are accessing, adding or inserting elements into an existing vector container, you can only use the member functions provided by the vector template class, with the exception of deleting the elements of the vec ...

It inherits from AbstractList and implements list, randomaccess and clonable interfaces. Vector inherits AbstractList and implements List; Therefo ...

I vector introduction vector document vector is a sequence container that represents a variable size array. Like arrays, vectors use continuous storage space to store elements. This means that you can use subscripts to access the elements of a vector, which is as efficient as an array. But unlike an array, its size can be changed dynamic ...
