- Write a program in C++, that creates a class Rock with a default constructor, a copy-constructor, an assignment operator, and a destructor, all of which announce to cout that they’ve been called. In main( ), create a vector<Rock> (that is, hold Rock objects by value) and add some Rocks. Run the program and explain the output you get. Note whether the destructors are called for the Rock objects in the vector. Now repeat the exercise with a vector<Rock*>. Is it possible to create a vector<Rock&>?You must create (in C++) two Crosswalk Signal objects from the class shown below to prove that your class works properly for GDOT, the first object should use the default constructor and the second object should use the overloaded constructor. Using the objects you just created in 1), call the method to change the light to the next in the sequence (in C++).Write a C++ code for the problem below. Problem: Write a class called profileID, which has data members firstName, lastName, age, and birthday. Instantiate an object ECE as an object of class profileID.
