Vector : A vector is a container which performs like an extensible array. The size of the vector is dynamic. The series of elements are stored using the same variable name. It uses random-access iterator. If an element is added or removed, it adjusts its size automatically, which accommodates the number of elements contained in the vector.

Vector:

A vector is a container which performs like an extensible array.

The size of the vector is dynamic.

The series of elements are stored using the same variable name.

It uses random-access iterator.

If an element is added or removed, it adjusts its size automatically, which accommodates the number of elements contained in the vector.

Expert Solution & Answer

Explanation of Solution

Emplacement:

The technique used by member function to insert new elements in a container is emplacement. When new object is inserted into a container it avoids creation of temporary objects in memory.

emplace() and emplace_back() emplacement member functions:

Two member function in a vector class uses emplacement technique namely: “emplace()” and “emaplace_back()”.

These two member functions avoid the creation of memory when new object is inserted into a container.
There is no need to instantiate the objects which are going to be inserted.
The objects are just passed as an argument into the emplacement function.
The emplacement function handles the creation of object and then forwards to the argument to its constructor.

Comparing “emplace()” and “emplace_back()” member function with “insert()” and “push_back()” :

The “insert()” and “push_back()” member functions creates a temporary memory when new objects are inserted into a container.

Whereas, the “empalce” and “emplace_back()” member function avoids the creation of memory when new objects are inserted into a container.
