Question

I just started learning classes in C++ and I get this error for the code below: conflicting declaration 'std::string PizzaOrder::toppings_offered'

Can someone explain what’s wrong with my code here?

class PizzaOrder
{
public:
    //all the toppings that are offered, constant array of strings
    static string toppings_offered[5];
    static double topping_base_cost;
};

string PizzaOrder::toppings_offered = {"onions", "bell peppers", "olives", "spinach", "tomatoes"};
double PizzaOrder::topping_base_cost = 0.50;

Answer 1

You forgot that toppings_offered is an array of strings, rather than a string:

string PizzaOrder::toppings_offered[5] = {"onions", ... };
//                                  ^
//                                  |

(BTW, I’d expect a pizza order to order toppings, not offer them. Could it be that your design still is a bit scrambled?)
