Create an ArrayInt class to provide safe integer arrays with bounds checking. Overload operator [] to return an element if it exists in the array, or throw an exception if it is outofBounds. Add other methods to ArrayInt, such as Resize (), RemoveElement (), and so on. Model the data comprising the array using a dynamically allocated array (that is, using int *contents) so that you can easily handle resizing. The code would begin as follows:

class ArrayInt // starting point for the class def. { // be sure to add: using std::to_string; private: // and also: using std::out_of_range; int numElements = 0; // in-class init. int contents = nullptr; // dynam. alloc. array
