Question
I need helpt on writing address book in C++
Following are the requirements for the address book.
// File: record.h
Definition of record.h
// File: llist.h
class llist
{
private:
record * start;
char filename[16];
int readfile();
int writefile();
record * reverse(record * );
void cleanup();
public:
llist();
llist(char[]);
~llist();
int addRecord(char[], char[], int, char[]);
int printRecord(char[]);
int modifyRecord(char[], char[], char[]);
void printAll();
int deleteRecord(char[]);
void reverse();
};
Requirements:
Define the two following constructors function but you may use either one in your main function
llist mylist; // Instance of class llist
llist mylist( "proj2.txt" );
You cannot change the class definition without consent
You may create any other functions you like or add to the menu in the interface.
You cannot use any of the C I/O functions. Use the C++ versions instead.
No global variables may be used.
Name may have spaces and addresses may have multiple lines (use getline).
Use ifndef directives for the C++ header files
deleteRecord will delete all records, including duplicates based on the name.
addRecord will create a record even if it already exists with the same name
addRecord must add the record to the end of the list
modifyRecord will modify all records with the same name
printRecord will print on the screen information for all records with the name specified
printAll will print the entire address book on the screen
A make file must be used.
New Requirements:
Implement the reverse method using recursion and add an option to the menu
This will reverse the list without printing it.
Overload the << operator so it replaces the calling of the printAll method in the user-interface. It should not call the printAll method.
Implement debug mode using preprocessor directives, instead of command line arguments.
