******************只是分号错了

#include <iostream.h>
class grade
{
int math;
int phy;
int che;
public:
void disp()
{
cout<<"数学="<<math<<"\n";
cout<<"物理="<<phy<<"\n";
cout<<"化学="<<che<<"\n";
}
friend class person; //分号是中文模式**************错误分号
};
class person
{
grade g;
int num;
char name[8];
char cl[20];
public:
void get_person()
{
cout<<"shu ru xuehao,xingming,banji:\n";
cin>>num>>name[8]>>cl[20];
}
void get_grade()
{
cout<<"shu ru shuxue,wuli, huaxue chengji\n";
cin>>g.math>>g.phy>>g.che;
}
