cout<<stu.name<<","<<stu.age<<","<<stu.score;这段代码什么意思

这段代码是用来输出一个名为stu的结构体变量中的成员属性(name,age,score)的值。具体来说,使用cout输出stu的name属性、逗号、age属性、逗号、score属性的值。其中,stu.name表示结构体stu的name属性,stu.age表示结构体stu的age属性,stu.score表示结构体stu的score属性。

设计学生类Student,成员数据包括学号(int Id)、姓名(char name[9])成绩(int score)。根据给定的main函数设计必要的成员函数。 main函数已给定,提交时只需要提交main函数外的代码部分。 #include<iostream> #include<cstring> using namespace std; //你提交的代码在这里 int main() { Student stu1; cout<<"Show object stu1:"; cout<<stu1.GetId()<<"-"<<stu1.GetName()<<"-"<<stu1.GetScore()<<endl; int no,s; char xm[9]; cin>>no>>xm>>s; Student stu2(no,xm,s); cout<<"Show object stu2:"; cout<<stu2.GetId()<<"-"<<stu2.GetName()<<"-"<<stu2.GetScore()<<endl; cin>>no>>xm>>s; cout<<"Reset and Show object stu1:"; stu1.Set(no,xm,s); stu1.Show(); cout<<"Reset and Show object stu2:"; stu2.Set(); stu2.Show(); return 0; }
```
#include<iostream>
#include<cstring>
using namespace std;
class Student {
private:
int Id;
char name[9];
int score;
public:
Student() {
Id = 0;
strcpy(name, "");
score = 0;
}
Student(int no, char* xm, int s) {
Id = no;
strcpy(name, xm);
score = s;

帮我检测一下代码#include<iostream> using namespace std; struct student { char name[50]; int num[20]; double c,m,e; }; struct student stu1={"Li Meimei",102,78,88,76566}; int main() { cout<<"数据成员名为"<<stu1.name<<endl <<"数据成员学号为"<<stu1.num<<endl <<"语文成绩为"<<stu1.c<<endl <<"数学成绩为"<<stu1.m<<endl <<"语文成绩为"<<stu1.e<<endl; }
这段代码有两个问题:
1. 结构体中的 num 数组只有 20 个元素,但是在初始化 stu1 时使用了一个长度为 5 的整数,这会导致数组越界。
2. 在输出学号时,应该使用 stu1.num 而不是 stu1.num[0]。
以下是修改后的代码:
```cpp
#include<iostream>
using namespace std;
struct student {
char name[50];
int num;
double c, m, e;
};
struct student stu1 = {"Li Meimei", 102, 78, 88, 76.566};
int main() {
cout << "数据成员名为" << stu1.name << endl
<< "数据成员学号为" << stu1.num << endl
<< "语文成绩为" << stu1.c << endl
<< "数学成绩为" << stu1.m << endl
<< "英语成绩为" << stu1.e << endl;
return 0;
}
```
