File Contents                  File format (organization)
The Long Walk                // Title of book
King, Stephen                // Author’s name

Write a function named Read_List to read the data for a list of books from a file (refer to the file format described above) and store them in an array of type Book. The array, its size and a file handler (assume the file is open and ready for reading) are passed to the function. The function returns the number of books read from the file. Assume there is enough space in the array for all the records in the file.  Must use the function developed for previous question to read data for 1 book (Read_Book() function).

Answer 1

int Read_List(Book a[],int n,ifstream in)
{
   int i=0;
   while(in && i<n)//runs untile i<n and file is not empty
   {
       //calling method to read data for 1 book
       Read_Book(a[i],in);
       i++;   //counting the number of books readed
   }
   return i;
}
