Answer 2

//vc6 pass
#include<stdio.h>
#include<string.h>
class student
{
public:
char* getid(){return id;}
char* getname(){return name;}
char* getphone(){return phone;}
char* getcollege(){return college;}

void setid(char* c){strcpy(id,c);}
void setname(char* c){strcpy(name,c);}
void setphone(char* c){strcpy(phone,c);}
void setcollege(char* c){strcpy(college,c);}
private:
char id[50];
char name[50] ;
char phone[50] ;
char college[50] ;
};

void main()
{
student stu;
stu.setid("01141011");
printf("%s\n",stu.getid());
stu.setname("Wang ning");
printf("%s\n",stu.getname());
stu.setphone("1399999911");
printf("%s\n",stu.getphone());
stu.setcollege("Bei Da");
printf("%s\n",stu.getcollege());
}

Answer 3

#include <iostream>
using namespace std;
class student
{
public:
char id,name,college;
public void change(char i char n char c)
{
}
}

int main()
{ char i,n,c;
change(i,n,c);
cout<<i<<" "<<n<<" "<<c<<endl;
return 0;
