c＋＋答疑为什么出错

#include
#include
using namespace std;
class product
{
public:
product(string name,double _price,int _store)
{
total_price += _price*_store;
total_store += _store;
}
static double get_total_price(){return total_price;)
static int get_total_store(){return total_store;}
static double total_store;
static int total_price;
};
double product::total_price;
int product::total_store;
int main()
{
product p1("p1",1,100);
product p2("p2",2,100);
cout <<product::get_total_price() <<endl;
cout <<product::get_total_store() <<endl;
return 0;
}

修改处见注释，供参考：

#include <iostream>
#include <string>
using namespace std;
class product
{
public:
    product(string name,double _price,int _store)
    {
         total_price += _price*_store;
         total_store += _store;
    }
    static double get_total_price(){return total_price;}//')'这里打成括号了
    static int  get_total_store(){return total_store;}

    static int  total_store; //数据类型错误
    //static double total_store;

    static double total_price;//数据类型错误
    //static int total_price;
};
double product::total_price;
int product::total_store;
int main()
{
    product p1("p1",1,100);
    product p2("p2",2,100);
    cout <<product::get_total_price() <<endl;
    cout <<product::get_total_store() <<endl;
    return 0;
}

是这样吗？

#include<iostream>
using namespace std;
class product
{
public:
    product(string name, double _price, int _store)
    {
        total_price += _price * _store;
        total_store = _store;
    }
    double total_store=0;
    int total_price=0;
    double get_total_price() {return total_price;}
    int get_total_store() { return total_store; }

};
int main()
{
    product p1("p1", 1, 100);
    product p2("p2", 2, 100);
    cout << p1.get_total_price() << endl;
    cout << p2.get_total_store() << endl;
    return 0;
}
