c++关于类的使用 求大神帮我看一下哪里错了

Question

#include <iostream>

#include <iomanip>

using namespace std;

class Student

{

private:

    string strname;

    int nindex;

    double  score;

public:

    string getstrname()

    {return strname;}

    int getnindex()

    {return nindex;}

    double getscore()

    {return score;}

    void setstrname(string strnewname)

    {strname=strnewname;}

    void setnindex(int nnewindex)

    {nindex=nnewindex;}

    void setscore(double newscore)

    {score=newscore;}

};

int main()

{Student stu1,stu2;

stu1.setstrname("张三");

stu1.setnindex(100);

stu1.setscore(90);

stu2.setstrname("李四");

stu2.setnindex(101);

stu2.setscore(70);

cout<<"学生成绩"<<endl;

cout<<left;

cout<<setw(10)<<"学号"<<setw(10)<<"姓名"<<setw(10)<<"成绩"<<endl;

cout<<setw(10)<<stu1.getnindex(100)<<setw(10)<<stu1.getstrname("张三")<<setw(10)<<stu1.getscore(90)<<endl;

cout<<setw(10)<<stu2.getnindex(101)<<setw(10)<<stu2.getstrname("李四")<<setw(10)<<stu2.getscore(70)<<endl;

    return 0;

}

类中的这几个 getXXX() 成员函数都是不需要参数的，你在调用它们时为什么要传参呢？   所以就错了啊...
