Question

select all that apply. which of the following are member functions of the vector class that use emplacement?

Answer 1

The member functions of the vector class that use the location are:

• Emplace ()
• Emplace_back()

Correct answer: letters C y D.

This is because these functions are more efficient than the insert() and push_back() functions because they do not require elements to be copied.

What are locator functions?

They are a type of insertion function used in vectors, which allows the user to construct and insert elements into a vector without making copies of the elements. This is achieved by using the constructors built into the vector to build the elements directly into the vector's internal storage, without the need to make a copy of the elements. This is more efficient than using a copy constructor, since only a single construction is needed.
