Question:

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