Vector functions in C++
--------------------
clear() // remove all the elements of the vector container
insert() // Inserts new elements before the element at the specified position
emplace() // Extends the container by inserting new element at position
erase() // Remove elements from a container from the specified position or range
push_back() // Push the elements into a vector from the back
emplace_back() // Constructs an element in-place at the end
pop_back() // Pop or remove elements from a vector from the back
resize() // Changes the number of elements stored
swap() // Swap the contents of one vector with another vector of same type. Sizes may differ.Copyright © 2021 Codeinu
