my program wont read my text files in??
When my program runs and i press 1 or 2 from the menu the function member_list or book_list runs but doesnt read any data from the text file it just prints out the cout statements a number of times. What i need it to do it display the records from the text file im reading into the program. Can anyone solve this problem ?
I believe i have opened them correctly in main() could it be that my functions to read them are wrong ?
please help??
Code:
#include <iostream.h>
#include <stdlib.h>
#include <string>
#include <fstream.h>
const int maxmembers = 1000;

struct cust
{
string surname;
string house_no;
string road;
string ID;
int books_borrowed;
};
struct books
{
string author;
string title;
string category;
string ISBN;
int loaned;
};
void member_list(cust c[])
{
for(int i=0; i< maxbooks;i++)
{
cout<< "Surname\t\tHouse No\t\tRoad\t\tID" << endl;
cout << c[i].surname << endl;
cout << c[i].house_no << endl;
cout << c[i].road << endl;
cout << c[i].ID << endl;
}
}
void book_list(books b[])
{
for(int i=0; i< maxbooks;i++)
{
cout<< "Author\t\tTitle\t\tCategory\t\tISBN" << endl;
cout << b[i].author << endl;

}
}
