这串代码哪里错了？拜托拜托

#include <iostream>
#include <string>
using namespace std;

   }

        string name;   //姓名
      double Salary; //月工资  
};

class Technican:public Emloyee{    //技术员类 
public:
      Technican(int no,string na):Emloyee(no,na)
       {
              hourlyrate=150;
            }
    void Print()
    {
          cout<<"技术员:"<<name<<" "<<"月小时:";
            cin>>workhours;

    M.Print();
    T.Print();
    S.Print();
    SM.Print();

    return 0; 

}

类SalesManager的构造函数错了
SalesManager(int no, string na) :Emloyee(no, na), Manager(no, na), SalesPerson(no, na)
{
ratio = 0.0005;
monthpay = 4000;
}
