Marks Store

Question

Extend the smartintarrayclass in smartintarrayclass.h and smartintarrayclass.cpp to include member functions that store and retrieve the (data of) the instance to and from a named file. The file name is passed to the member function as a simple C++ string. This can be done either by directly modifying the smartintarrayclass, or by defining a new derived storeintarrayclass that inherits from smartintarrayclass.

Change the MarksClass.cpp program to:

Prompt the user whether the marks should be read from the user or from a file.
If reading from file, prompt the user for a file name.
Read the marks from the specified source.
If read from user, prompt the user for a file name and store the marks to the file.
Output the total and average of the marks.

Answer

storeintarrayclass.h
