Question

The Cupid matchmaking Service maintains two files -
one for the male clients and another for female clients.
Each file contains a client ID, last name, first name, and address.
Each file is in client ID order.
se the provide pseudocode to write a C++ application that
merges the two files into one file containing a list of all clients,
maintaining ID member order.
