1) Do you think it is possible to create another constructor with the same set of parameters? For example, adding the following constructor to Volunteer. Place a check (✓) beside your answer. Volunteer(): name_("Default"), branch_("CSU Long Beach") { } Yes, because you can overload constructors much like how you overload member functions. No, because the program will not know which constructor to use. No, because the body of the constructor is empty. 2) Much like constructors, member functions can also be overloaded. Write the name of Volunteer's overloaded member function. Take note that member function overloads need to have the same return type. 3) How do you think the compiler knows which member function overload it should call? Place a check (✓) beside your answer. It checks the name of the member function that was called. It compares the number of arguments and their data types with the member function's parameters. It always calls the overload with the least number of parameters.

Problem 2: Route Planning You are on the development team for a Route Planning application. The team has already developed a class named NavigatorApp for storing and displaying the graph representing the road network. This class has a void displayShortestPath() function which takes the source and destination vertices of the trip and displays the shortest route between them. Using the strategy pattern, draw a class diagram of the system which will allow for the NavigatorApp to display the shortest driving, walking, or cycling route when the displayShortestPath() function is called. You can assume that another developer is in charge of making sure the appropriate strategy is correctly set and for calling the displayShortestPath() function Starter code /* Modify NavigatorApp (if necessary) */ class NavigatorApp { private: Graph map; public: void displayMap(Window * window); void displayShortestPath(Vertex source, Vertex destination, Window * window); /* write pseudo code for this function…

Network Class The Network class represents a network of people that are connected to each other and are able to contact and send messages to each other through the network. Create a Network class with the following: Member Variables A Network has just one private member variable: phonebook_ - a std::map which maps from a std::string for a person's name, to the std::shared_ptr<Phone> object that belongs to that person. Constructor You do not need to explicitly define a constructor. The default constructor will implicitly be created for us by the compiler, initializing the phonebook_ to an empty map. AddPhone Create a function AddPhone that accepts a std::shared_ptr to a Phone and inserts that Phone to the phonebook_. The key is the name of that phone's owner, and the value is the shared pointer to the Phone. SendMessage Create a function SendMessage that accepts a std::shared_ptr to a Message and a const reference to a std::string representing the intended recipient of this…

build a student class implement the student class with the following instance variables: * id * firstName *lastName *dateOfBirth * Major create an __init__ function adn initialize all the fields make the "major" an option field and set a default value to "undefined" create a setter and getter function for all these five variables create another function: "print_student_info()" which prints 5 pieces of information: id, first name, last name, date of birth, and major. Make sure to have proper formatting done for printing these 5 things. Use the student class Task 1: create an empty list named "all_students" Task 2: create a variable named "id" and initialize it to 100 (some default value to start with, next id would be 101) Task 3: ask the user for input "How many students:" Task 4: Now run a for loop based on that input number and do the following things for each iteration: - get input of student's first name, last name, date of birth, and major - user should be able to skip the…
