C++ Programming (7th Edition)

Recall that in C++, there is no check on an array index out of bounds. However, during program execution, an array index out of bounds can cause serious problems. Also, in C++, the array index starts at 0. Design and implement the class myArray that solves the array index out of bounds problem and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements: myArray list(5); //Line 1 myArray myList(2, 13); //Line 2 myArray yourList(-5, 9); //Line 3 The statement in Line 1 declares list to be an array of 5 components, the component type is int, and the components are: list[0], list[1], ..., list[4]; the statement in Line 2 declares myList to be an array of 11 components, the component type is int, and the components are: myList[2], myList[3], ..., myList[12]; the statement in Line 3 declares yourList to be an array of 14 components, the component type is int, and the components are: yourList[-5], yourList[-4], ..., yourList[0], ..., yourList[8]. Write a program to test the class myArray.
