职员类Worker（C++）

定义一个Worker（职员）类，该类有name（姓名）、position（职位）、salary（月薪）等私有数据成员。该类有两个私有静态数据成员：count用于统计雇员总人数、totalSalary用于计算月应发薪酬总数。为该类定义构造函数，构造函数要负责对静态数据成员的值进行调整。再定义一个静态函数成员void printSalary ()，该函数用于输出静态数据成员的值。定义你认为必要的其它函数。main函数已经写好，请根据main函数的内容完成该类的定义。

int main(){

string name;

string position;

double salary;

cin>>name>>position>>salary;

Worker w1(name,position,salary);

cin>>name>>position>>salary;

Worker w2(name,position,salary);

cin>>name>>position>>salary;

Worker w3(name,position,salary);

cin>>name>>position>>salary;

Worker w4(name,position,salary);

cin>>name>>position>>salary;

Worker w5(name,position,salary);

Worker::printSalary();

return 0;

}
