设计一个学生类Student，成员数据包含学号（int Id），姓名（char name[40]）和成绩（int score）。 程序功能：首先读入n个学生数据；然后按照学生成绩升序排列，如果有成绩相同的则按照学号升序排列；最后输出所有学生的信息。 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() { int i,j,n; Student t; cin>>n; Student *stu=new Student[n]; for(i=0;i<n;i++) cin>>stu[i]; for(i=0;i<n-1;i++) for(j=0;j<n-i-1;j++) if(stu[j]>stu[j+1]) { t=stu[j]; stu[j]=stu[j+1]; stu[j+1]=t; } for(i=0;i<n;i++) cout<<i+1<<":"<<stu[i]<<endl; delete[]stu; return 0; }输入3 1001 Alice 85 1002 White 75 1003 Tom 90输出1:id=1002,name=White,score=75 2:id=1001,name=Alice,score=85 3:id=1003,name=Tom,score=90请补充完整代码
