//A wholesale book dealer needs a program to write invoices for book
orders that
//he takes over the phone. Each order usually consists of multiple
copies of several
//book titles. The program should ask the user if there is an order to
process.
//If the user responds yes, the program should then ask for the price of
the first book
//in the order and the number of such books. The program should then
display the cost of
//these books, including a 7.5% sales tax. Then it should ask for the
price of the second
//book in the order and the number of such books, and display the cost
of these books. The
//program should continue in this way, processing the books in the first
order. When there
//are no more books in the order, the program should display the total
cost of the order.
//Then the program should ask if there is another order. If there is
one, the program should
//process it as just described. If there are no more orders, the program
should display the
//total number of orders processed, the total number of books sold, and
the total receipts.
//Use nested while loops
my solution is following which doesn't work properly!
#include <iostream>
using namespace std;
int main()
{
double price, cost, total_cost=0, total_receipt=0;

int number, total_number=0, total_order=0;
double response;
cout << "~~~~~BOOKSTORE~~~~~~" << endl;
cout << "DO YOU WISH TO PROCEED (0 OR 1): ";
while ((response=(cin.get())) == '1')
{
cout << endl;
cout << "ENTER PRICE OF THE BOOK: ";
cin >> price;
cout << "ENTER COPIES OF THE BOOK: ";

total_cost += cost;
