Consider the definition of a class that acts like an array with bounds-checking. class my_array { }; private: public: int size; int *a; my_array (int s): size (s) { a = new int[size]; } int &operator[] (int i); int get_size() { return size; } a) Give the code for my array's operator[] method, as one would define it outside the class. (3 Marks). b) Overload the insertion ( < >) operators so that they behave as follows: i. 11. The insertion operator outputs all the elements of the array, separated by spaces. to the output stream. (3 Marks) The extraction operator reads the elements of the array from the input stream. (3 Marks).
