Create a class in C$++$ called $$CVector$$ with an STL vector structure defined as a private data member. This class should have the following:

A$.$ A default constructor.

B$.$ A $$setVector$$ method that can set the class data member by passing a vector as a parameter.

C$.$ An $$add$$ method can be used to add the vector within the $$CVector$$ object to another object of the same class $($remember$,$ the method adds vectors of the same size$).$ The adding should add the corresponding values of the two vectors to each other.

D$.$ A $+$ operator function can have the same effect as the $$add$$ method.

E$.$ A $$show$$ method that prints out the content on the Vector data member.

F$.$ Your main function should read and reflect the code below in Figure $3$:
