我正在制作这个比萨饼程序，但我不断收到向量的这个错误。它一直说“错误：与运算符<<不匹配”
这是我的代码
披萨.h
#include <iostream>

using namespace std;

friend void display(Pizza,Order);

char typeofPizza;

public:
void setTypeOfPizza(char);
string getTypeOfPizza();
void setSizeOfPizza(char);
string getSizeOfPizza();
void setToppings(int);
int getToppings();
double calculate();
void loopPizza(int);
void displayPizza();
};
class Order
{

//int pizzaOrderd=1;
public:

我没有做错什么我正在尝试将 displayPizza 函数添加到向量中的每个位置。除非我不允许这样做。任何人都可以请教育我。
