    I didn't think we were here to complete your work. But if you have a problem with a certain part that would make sense, ie. you say "I dont know how to access the struct I created", "I'm not sure how to get it to ask if it wants to buy more books and quit on n"

    Code:
    #include <iostream> 
    #include <cstdlib> //use these headers
    
    struct bookshop 
    { 
      int ISDN; 
      char title; 
      int price; 
    }; 
    
    void printbook (bookshop book); 
    
    int main() 
    
    { 
    char continue = 'y'; 
    bookshop book[20]; //max 20
    int totalPrice = 0;
    int index = 0;
    
    while (continue == 'y') {
      cout <<"ISDN: "; 
      cin >> book[index].ISDN; 
      cout <<"Title: "; 
      cin >> book[index].title; 
      cout <<"Do you want to continue: "; 
      cin >> continue; 
    
      totalPrice = totalPrice + book[index].price;
      ++index;
    }
    
    // do the reciept part here
    
    return 0; 
    }
    I did a little more than I meant to do, but I'm not works either I also changed the headers, cstdlib and iostream (without .h) are the C++ versions, and are standard (updated, won't become deprecated in near future).
    Warning: Have doubt in anything I post.
