帮帮忙看看到底哪儿错了
#include<iostream.h>
#include<string.h>
class student
{
char num;
char name[5];
char sex;
char schoolname[20];

public:
student(char n,char *m,char s,char *sn)
{
num=n;strcpy(name,m);sex=s;strcpy(schoolname,sn);
}
void show()
{
cout<<"num:"<<num<<endl;
cout<<"name:"<<name<<endl;
cout<<"sex:"<<sex<<endl;
cout<<"schoolname"<<schoolname<<endl;
}
};

class bystudent:public student
{
char xw[10];
public:
bystudent(char n,char *m,char s,char *sn,char *x):student(n,*m,s,*sn)
{
strcpy(xw,x);
}
void show()
{
student::show();
cout<<"xuewei:"<<xw<<endl;
}
};

void main()
{
student s1("001","ÀöÀö","n","ÖØÇì´óѧ");
s1.show();
bystudent b1("001","ÀöÀö","n","ÖØÇì´óѧ","±¾¿Æ");
b1.show();
}

啥问题？
[解决办法]
bystudent(char n,char *m,char s,char *sn,char *x):student(n,m,s,sn)//mark
[解决办法]
char num 这是你定义的数字类型 而你赋值是001 不是字符型
char sex 字符型 赋值用小括号‘ ’
