I need to utilize a pointer in Greet.h

In this program, we ask a user to type in their name and we provide a greeting. We have two types of greetings, which are both defined in greetings.cpp. One is polite and the other one is rude. Suppose that we wish to be rude to everyone whose name starts with the letter "J", and polite to everyone else. This does not represent the real views of members of the teaching team To implement the above policy, we use a function called greet, which takes in a string, representing the name of the person we are supposed to greet, and a pointer to a function, which determines how the person is greeted
