public:
    void set_data(int n, char *p,char s);
    void display( );
private:
    int num;
    char name[20];
    char sex;
};
void Student::set_data(int n, char *p,char s)
{
    num=n;
    strcpy(name,p);
    sex=s;
}
void Student::display( )
{
    cout<<"num: "<<num<<endl;
    cout<<"name: " <<name<<endl;
    cout<<"sex: " <<sex<<endl<<endl;
}
int main()
{
    Student stud1,stud2;
    stud1.set_data(1,"John",'f');
    stud2.set_data(2,"Mary",'m');
    stud1.display();
