Question

如何实现客户机（CLIENT）类?

Answer 1

//client.h
#ifndef _CLIENT_
#define_CLIENT_

#include<iostream>
#include<string.h>
usingnamespacestd;

classCLIENT
{
staticchar*ServerName;
staticintClientNum;
public:
CLIENT(){ClientNum++;}
~CLIENT(){ClientNum--;}//delete ServerName;}
staticvoidChangeServerName(char*name);
staticchar*getServerName();
staticintgetClientNum();
};
#endif

//client.cpp
#include"client.h"

voidCLIENT::ChangeServerName(char*name)
{
ServerName=newchar[strlen(name)+1];
strcpy(ServerName,name);
};
char*CLIENT::getServerName()
{
returnServerName;
}
intCLIENT::getClientNum()
{
returnClientNum;
};

//test.cpp
#include <iostream>
usingnamespacestd;
#include"client.h"

intCLIENT::ClientNum=0;
char* CLIENT::ServerName="HPC";

intmain()
{
CLIENT a,b;
cout<<CLIENT::getClientNum()<<endl;
cout<<CLIENT::getServerName()<<endl;
CLIENT::ChangeServerName("CNNIC");
cout<<CLIENT::getServerName()<<endl;
}
