写得好辛苦，别忘了给分啊！

刚刚看C++.
如果你能写出这么复杂的类来，为什么不多花点时间看看容器的使用。
应该只要先定义一个容器类。
vector stu;
push_back（）满足输入。
然后，
利用stu.begin() （这个好像和引用相似）读取数据的内容，进行一个排序。

输出的模块（完全不会了）

class student{
public :student(){}
public :
student(int eng,int dig,int mod,int pow,int p,int ma,int electr,int prac){
english=eng;
digitalElec=dig;
modian=mod;
powerMachine=pow;
pe=p;
mazhe=ma;
electrican=electr;
practice=prac;
cout<<"\t\t初始话完毕！";

}

~student();
void caculate();
void caculateReal();

public :int （这里修改）english,digitalElec,modian,powerMachine,pe,mazhe,electrican,practice;
}
;

void student::caculate(){
double sum=0; double average=0;
cout<<"\t请输入英语:";
cin>>english;

cout<<"\t请输入数电:";
cin>>digitalElec;
cout<<"\t请输入模电:";
cin>>modian;
cout<<"\t请输入电机:";

cout<<"\t请输入体育:";
cin>>pe;
cout<<"\t请输入马哲:";
cin>>mazhe;
cout<<"\t请输入电工电子:";
cin>>electrican;
cout<<"\t请输入实习:";
cin>>practice;
sum=english*4+digitalElec*4+modian*4+powerMachine*3.5+pe+mazhe*3+electrican+practice*2;
average=sum/(4+4+3.5+3+1+3+1+2);
cout<<"平均成绩是："<
} //你的成绩已经在构造函数里输入了，这里应该只要直接调用啦。
student ::~student(){

cout<<"\t\t析构运行，程序结束";

}

//main 函数caculate.cpp
#include
#include "student.h"
void main(){
student s;

s.caculateReal();

}

越看越乱。！！！我还以为你写出了一个好的类呢。原来是这样····

30太少了。。。。。懒得写

找你老师吧
