Libary book store program with fstream

p33n kenan (41)
hi

I need to make a book store libary for my dad because he said he wanted one for his small schoollibary (where he works) and I am on informatics school so I should made it. But I have a real problem with reading from files and writing to it.

This is what i want it to do:

cout<<"type the number for the action "<<endl;
	cout<<"1.    add book "<<endl;
	cout<<"2.    search book by name "<<endl;
	cout<<"3.    search book by bookcode "<<endl;
	cout<<"4.    search book by author "<<endl;
	cout<<"5.    search book by editor "<<endl;
	cout<<"6.    search book by date "<<endl;
	cout<<"7.    check registrations "<<endl;    //if the book is taken or not
	cout<<"8.    make registrations "<<endl;    //if the book is taken or not
	cout<<"9.    save data "<<endl;
	cout<<"0.    quit program with storing data "<<endl;
	cout<<"10.  quit without storing data "<<endl;


After that there is a simple switch to choose.

I am using this structurefor the seperate books

struct libary{
	
char name[100];
char author[50];
char editor [30];
int code;
bool regis;   //if it is taken or not
	
struct date{
	
	int day;
	int month;
	int year;
	}date;
	
};


But how do i write this to a .txt file so I can make it search for the books the next time after he opens the program. can anyone help me whth this. the structure is made in a array in which every single book has his own spot.

thanks for reading

edit: here is as far as i got with the code without using files:

I have seen a reply by mail but i can't see it here so it might look wierd for some people but
first off all thank you for the tips. the program is not on a server. i will change it to a string as you told me to. the date thing in the structure is cool, i've done it like that before. i thing nothing but the "regis" variable should be able to be edited after. but there will not be a way to edit the others after it.
