/*Implement a class CppArray which is identical to a one-dimensional C++ array (i.e.,
the index set is a set of consecutive integers starting at 0) except for the following :
1. It performs range checking.
2. It allows one to be assigned to another array through the use of the
assignment operator (e.g. cp1= cp2)
3. It supports a function that returns the size of the array.
4. It allows the reading or printing of array through the use of cout and cin.
