为什么始终不能通过编译

Question

#include<iostream>

using namespace std;

class CStudent

{

public:

CStudent(char nam,int num,int gra1,int gra2,int gra3):name(nam),number(num),grade1(gra1),grade2(gra2),grade3(gra3){}

void display()

{

cin>>name>>number>>grade1>>grade2>>grade3;

int z=(grade1+grade2+grade3)%3;

cout<<name<<number<<grade1<<grade2<<grade3<<z<<endl;

}

private:

char name;

int number;

int grade1;

int grade2;

int grade3;

};

int main()

{

CStudent stud1;

stud1.display();

return 0;

}

Answer 1

你好。在main函数里面，CStudent stud1;    //你没有传入参数，当然编译不过了。 CStudent stud1('a', 123, 5, 6, 7);    //你要像这样，传入对应的参数才可以
