输入N个学生数据：学号 姓名 成绩 要求输出这些学生数据并计算平均分（通过对象数组来表示

用C++写的！谢谢了！

1楼你有1个error 但是很多行都显示要改 我改不来啊

//首先定义student类
class Student{
private:
int id;
string name;
float grade;

public: Student(){}
Studnet(int id, string name, float grade){
this.id = id;
this.name = name;
this.grade = grade;
}
void setId(int id){
this.id = id;
}
void setName(string name){
this.name = name;
}
void setGrade(string grade){
this.grade = grade;
}
int getId(){
return id;
}
string getName(){
return name;
}
float getGrade(){
return grade;
}
}

主函数如下：
void main(){
cout << "请输入想要学生的数量：" << endl;
int num;
cin >> num;
Student *stu = new Studnet[num];
float sum = 0;
for(int i = 0; i < num; i++){
int id;
string name;
float grade;
cout << "请输入第" << i + 1 << "个学生的id：";
cin >> id;
cout << "请输入第" << i + 1 << "个学生的姓名：";
cin >> name;
cout << "请输入第" << i + 1 << "个学生的得分：";
cin >> float;
stu[i].setId(id);
stu[i].setName(name);
stu[i].setGrade(grade);
sum = sum + grade;
}
for(int j = 0; j < num; j++){
cout << stu[j].getId() << " " << stu[j].getName()
<< " " << stu[j].getGrade() << endl;
}
cout << "平均分是：" << sum / num << endl;
}

可以私聊我~
