Array index out of bounds

Please assist with the following problem. I am totally lost with this so if you could also include statements telling me what you did, I would appreciate it. The entire chapter talks about array index out of bounds which has completely confused me and there are no examples in the book to help. If you could complete this program, it will help me to better understand how this works and what it is used for.

Program Problem

Design and implement the class myArray that solves the array index out of bound problem and also allows the user to begin the array index starting at any integer, positive or negative. Every object of the 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<int> list(5); //Line 1
myArray<int> myList(2,13); //Line 2
myArray<int> 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 componest are:
yourList[-5], yourList[-4], ..., yourList[0], ..., yourList[8].

Write a program to test the class myArray.

C++ - arrays

Create a C++ class that implements a "safe" array, where the arrays bounds are checked before accessing its elements. The class constructor must accept an integer parameter and create a dynamic array of that size for storing integers, implemented as a vector. The constructor must initialize all array elements with 0. Add two methods get(int) that returns the i-th element of the array and set(int) that uses return by reference for setting the corresponding array element, whose index is passed as the parameter. The method must allow to be used in the left-hand-side of assignment operator like array.set(i) = 5;. Report an error if the array index is out of bounds.

In the main() method, create an array instance of size n provided by the user, assign its values to 1,2,...,n and print them out.
