hi
I have a project due this Monday to make an address book. need some help with that.I have some code with me but it is not working. please help me if you can. i have attached a copy of the same and given description below.
program description:
develop a program for an address book.single entry in an address book is called a contact, which can have any of the following fields,
1. first name 2. last name 3. nickname 4. email1 5. email2 7. phone1 8. phone2 9. address 10.website 11.birthday 12.notes
a contact must have at least one of the first four fields to be valid.in the address book the user should be able to
1.add a contact
2.display all contacts sorted by a chosen field
3.display details of a single contact
4.remove a contact
5.find all contacts matching a keyword in a given field
6.modify a contact
7.export the address book to csv format file
8.exit the program
when the program is executed it takes a single command line argument:the name of the input file from which it reads an address book. all the modifications should be saved to the same original file on exit.
-----------------------main menu---------------------
[a] add
[b] display sorted by
[c] display details of contact
[d] remove contact
[e] modify contact
[f] export to csv format
[g] exit
the code I have is not working. please help.here is the code
