Scientists in a certain laboratory are working with a linked list class that uses recursion to compute its size. the scientists know that an empty list has size 0, so they never ask a linked list to compute its size when the list is empty. under these circumstances,
a. the recursive method should still handle the base case of an empty list, because it will still occur even though the scientists never ask for the size of an empty list and the recursive method can be modified to use a list of size 1 as the base case are both correct
b. the recursive method can become more efficient by eliminating the test for a base case
c. the recursive method should still handle the base case of an empty list, because it will still occur even though the scientists never ask for the size of an empty list
d. the recursive method can be modified to use a list of size 1 as the base case

Consider the following declarations (1, 2, 3, 5, 7)class bagtype{public: void set(string, double, double, double, double); void print() const; string getstyle() const; double getprice() const; void get(double, double, double, double); bagtype(); bagtype(string, double, double, double, double); private: string style: double l; double w; double h; double price; }; a.) write the definition of the number function set so that private members are set according to the parametersb.) write the definition of the member function print that prints the values of the data membersc.) write the definition of the default constructor of the class bagtype so that the private member variables are initialized to "", 0.0, 0.0, 0.0, 0.0, respectively d.) write a c++ statement that prints the value of the object newbag.e.) write a c++ statement that declares the object tempbag of type bagtype, and initialize the member variables of tempbag to "backpack", 15, 8, 20 and 49.99, respectively
