5. Slightly complicated the first task, adding condition.

   #include
   using namespace std;
   int main()

   {
   int quan_coffee, quan_chocolate, quan_milk;
   float price_coffee, price_chocolate, price_milk, money, result_coffee, result_milk, result_chocolate, result_all;

   cout << "How much money do you have?" <> money;
   cout << "How many packets of milk would you like to buy?" <> quan_milk;
   cout << "How many jars of coffee would you like to buy?" <> quan_coffee;
   cout << "How many bars of chocolate would you like to buy?" <> quan_chocolate;
   cout << "What's price for one bar of chocolate?" <> price_chocolate;
   cout << "What's price for one jar of coffee?" <> price_coffee;
   cout << "What's price for one packet of milk?" <> price_milk;

   result_chocolate = price_chocolate * quan_chocolate;
   result_coffee = price_coffee * quan_coffee;
   result_milk = price_milk * quan_milk;

   result_all = result_chocolate + result_coffee + result_milk;

   cout << "You have to pay " << result_all <= result_all) {
   float surr;
   surr = money – result_all;
   cout << "Your surrender is " << surr << "$" << endl;
   }
   else {
   cout << "Sorry, but you don't have enough money" << endl;
   }
   }
