小女子初学编程，遇到的问题不少，希望各位大神耐心指教。。非常感谢！

Question

题目：声明字符型静态数据成员ServerName,保存其服务器名称;声明整型静态数据成员ClientNum,记录已定义的客户数量;定义静态函数ChangeServerName()改变服务器名称.在头文件client.h中声明类,在文件clent.cpp中实现,在文件test.cpp中测试这个类,观察相应的成员
下面是我写的程序：
#include
using namespace std;
class CLIENT
{
public:
CLIENT(char name,int num)
{
ServerName=name;
ClientNum=num;
}
CLIENT(CLIENT &p);
~CLIENT() {}
void showServerName() {}
void showClientNum() {}
void showChangeServerName();
private:
static char ServerName;
static int ClientNum;
};

#include"client.h"
CLIENT::ServerName(char name)
{
ServerName=name;
}
CLIENT::ClientNum(int num)
{
ClientNum=num;
}
char ServerName='I';
int ClientNum=0;

#include
#include"text.h"

int main()
{
CLIENT n(7,'W');
cout<<"已定义客户数量:"<<n.showClientNum()<<endl;
n.showClientNum();
cout<<"服务器名称改为:"<<n.showChangeServerName()<<endl;
n.showChangeServerName();
}

在头文件client.h中声明类:

class CLIENT
{
public:
CLIENT(char name,int num);
~CLIENT();

char getServerName() ;
int getClientNum();
static void ChangeServerName(char newName);

private:
static char ServerName;
static int ClientNum;
};

在文件clent.cpp中实现:

CLIENT::CLIENT(char name,int num)
{
ServerName=name;
ClientNum=num;
}
CLIENT::~CLIENT() {}

char CLIENT::getServerName()
{
return ServerName;
}
int CLIENT::getClientNum()
{
return ClientNum;
}
void CLIENT::ChangeServerName(char newName)
{
ServerName = newName;
}

在文件test.cpp中测试这个类,观察相应的成员:

#include
using namespace std;
int main6()
{
CLIENT n(7,'W');
cout<<"qqqqq:"<<n.getServerName()<<endl;
cout<<"aaaaa:"<<n.getClientNum()<<endl;
n.ChangeServerName('X');
cout<<"qqqqq:"<<n.getServerName()<<endl;
cout<<"aaaaa:"<<n.getClientNum()<<endl;
}
