CS 23001 Spring 2017 Page 4 of 5 M. Decker (25pts) Write a class for the ADT darray. You must use a dynamic array of int. You must implement the 4 methods below (that are not already implemented). Each should behave as one would expect in C++. The assignment must implement standard copy semantics. 6. //CLASS INV: data->int [ cap] && cap >= 0 class darray f private: int * data; int cap; public: darray darray darray darray() operator= () : data(0), cap (O) t/I darray of capacity o. (int); (const darray&); //1) darray of capacity n. 1/2) Copy Constructor //3) Destructor //4) Assignment darray& (darray)
