Enum and Struct Program Help

[hippokrates]

Write a program that will manage a simple address book. The program should allow you to view and search existing entires as well as add new entries. The data should be stored in a file structured so that a person's first name, last name, and phone number are stored on one line separated by commas and the next line has their address.

Additional requirements:

The program should allow the user to make repeated requests until they choose to exit
The program should find multiple matches if necessary
The program should have an option to print out a list that just includes Name and Phone Number
The program should use at least two struct types and one enumerated type

So I made a program that meets most of the requirements above, but I don't know how to implement enum and struct into it. I don't know how to use them and I'm scared that I will mess up my current program. This is the program I have so far.

string uppercaseString(string);
void extraSpaces(string&);

[mike9407]

struct Person{
string firstname;
string lastname;
int phonenumber;


};

for struct u can do like that,for the enum i am not very sure about that
