(C++) Please help, I'm stuck on class template arrays. How is the following reimplemented into a class template with a corresponding main program?

The problem:

Reimplement class Array from the following excerpt as a class template. Also write a main driver program that: 1) Asks the user for integer values, stores them in an integer Array, and then prints the values stored in the integer Array 2) Asks the user for string values, stores them in a string Array, and then prints the values stored in the string Array
