#include<iostream.h>
class user
{
protected:
char*user_name;
int user_password;
public:
void set_member(char*name,int password)
{
user_name=name;
user_password=password;
}
void show_user(void)
{
cout<<"请输入你的姓名\n";
cin>>user_name;
if(user_name!=name)
cout<<"查无此用户\n";
else
cout<<"请输入密码\n";
cin>>user_password;
if(user_password!=password)
cout<<"你的密码不正确，请你重新输入\n";
}
};
void main(void)
{
char*name,int password;
cout<<"请输入你的姓名\n";
cin>>name;
int i;
for(i=1;i<=3;i++)
cout<<"你输入的次数过多，请查清后再取\n";
user o;
o.set_member(n="taoshucheng",p=851018);
o.show_user;
}
以上是我编的程序，可是就是运行不起来，帮忙，看看

有很多的地方有问题
#include<iostream.h>
class user
{
protected:
char username[20];
int userpassword;

public:
int set_member(char name[],int password);
};
int user::set_member(char name[],int password)
{
int p=0;
cout<<"请输入你的姓名\n";
cin>>username;
int w=strcmp(username,name);
if(w!=0)
cout<<"查无此用户\n";
else
cout<<"请输入密码\n";
cin>>userpassword;
if(userpassword != password)
{cout<<"你的密码不正确，请你重新输入\n";p=1;}
return p;
}

void main(void)
{

int c=0;
user o;
for(int y=0;y<3;y++){
int j=o.set_member("taoshucheng",851018);
if(j==0){break;}
}
}

class user

int user_password;
public:
void set_member(char*name,int password)
{
strcpy(user_name,name);
user_name[strlen(user_name)]='\0';
user_password=password;
}
void show_user(void)

char name[20];
int password;

if(user_password!=password)

}
};
。。。。改不下去了。。建议楼主把数组与指针那章反复的看反复的练习。另外在写程序之前先把思路整理好。

我也糊涂了，show_user少了个}

恭贺我们CUser v1.0发布

还是那句话说的对呀，专业程序员没有耐心和细心是不行嘀
