Question

Rewrite C++ Program #5 to use the C++ string class vs. C strings.

Your solution must be an object-oriented C++ program (i.e. a class and a main function to use it).

You must use files for both your input and output as stated in the textbook.

Execute your C++ program first for a client sort (to be indicated by option 1) and then for a business sort (to be indicated by option 2).

Original question:

To keep track of your clients in an orderly manner you need a program that can arrange them alphabetically by name or by business type. Write such a program using bubble sort. The input specifications are to:

Read the client and business from a file.

Read the requirement of sorting according to name or business from the keyboard.

The output specification is to put the arranged list into an output file.
