Programming Forums - Output A Linked List To A Binary File?

I need to read and write a linked list to a binary file so that it may be kept throughout the life of the program, but I'm having a hell of a time and my sourcecode doesn't work and I can't figure it out.
PLEASE HELP!

void write();

void read();

int ctr=0;//for lazy programming

int _tmain(int argc, _TCHAR* argv[])

{



int choice=0;

read();

while(choice!=4){

cout<<"Welcome to my program!\n";

cout<<"1. Add a person\n";

cout<<"2. Show everyone\n";

cout<<"3. Delete someone\n";

cout<<"4. Quit\n";

cout<<"?:\n";

cin>>choice;

if(choice==1){

//node::display();

person* a = new person();

} else if(choice==2){

node::display();

} else if(choice==4){

break;

} else if(choice==3){

int who;

cout<<"\nWho? ";

cout<<"Person "<<x<<endl;
