请问哪里出错了呀
#include<iostream>
#include<string>
using namespace std;
class Product{
public:
void set(string name){
cout<<"该产品名字为:"<<name<<endl;}
void wlh(string name,int price){cout<<"该产品名字为:"<<name<<"产品价格为:"<<price<<endl;}
void zc(string name,int price,int data){cout<<"该产品名字为:"<<name<<"产品价格为:"<<price<<"出产日期为:"<<data<<endl;}
};
int main(){
Product food;
food.set(chicken);
food.wlh(chicken,10);
food.zc(chicken,10,1995);
return 0;
}
