Phonebook directory

[tweaktwe]

Hey, i need help with my phonebook directory, my code is fine and working perfectly, but i need help adding the name "Firstname, lastname". my code only accepts one name. and i also have to search the contact using lastname. i think i can use Map<String,List<String>> for that but i need help with adding two names.

// Phonebook directory Program

                return 1; //Indicates success
            }
            else
                return 0; //Indicates failure
        }

        //Search

*********************************************************
I updated your class a little ... Left the int main() for you to do. For the most part all you have to do is update the main to accept the last name etc...

1. There is no reason to have stdlib.h .. it's the same as using namespace std;
2. All you had to is add "last name" and implement it every time your ask for first name.
btw .... You should optimize your code and fix your class format if you're in the mood..... anyway good luck and I hope this helps..

thank you! i did and it's giving me error at //Check whether name exists i try to put temp_lastn but it's still giving me error. unfortunately my pc doesnt allow me to view what my error is. and i used the #include stdlib for "cls" (clear screen without system)

[tweaktwe]

nevermind, i see my error. thanks
