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;
}
