Arglongest (L) Write the function argLongest that, given a nonempty list of strings, finds the index of the longest even-length string that ends with ing. It takes a list of strings L as input and returns an integer, the index of the longest string in L with a suffix ing of even length. If there are many longest strings, return the index of the first one. If there are no such strings, return the index -1. Finding the index is more valuable than finding the element: you can quickly retrieve the element using the index, but you cannot quickly retrieve the index using the element. So we want to get in the habit of computing indices of elements, not elements.

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
