class student:public person
{
private: int score;
string department;
public:
student(int i,string n,char s,int a,int sc,string d):
person(i,n,s,a)

Answer 1

// 定义部分因为粗心丢了个大括号
class person //1028.h
{
private:
int id;string name;char sex;int age;
public:
person(int i,string n,char s,int a )
{
id=i;
name=n;
sex=s;
age=a;
}
void print()
{
cout<<"id:"<<id<<endl;
cout<<"name:"<<name<<endl;
cout<<"sex:"<<sex<<endl;
cout<<"age:"<<age<<endl;
} // 丢了个大括号
};
