阅读以下说明和C++程序，将应填入(n)处的字句写在对应栏内。
【说明】
字符串在程序设计中扮演着重要角色。现需要设计字符串基类string，包含设置字 符串、返回字符串长度及内容等功能。另有一个具有编辑功能的串类edlt_string，派生于string，在其中设置一个光标，使其能支持在光标处的插入、删除操作。
【程序】
include ＜iostream.h＞
include ＜stdio.h＞
include ＜string.h＞
class string
{
int length;
char *data;
public:
int get_length() {return length;}
char *get_data() {return data;}
~string() {delete data;}
int set data(int in_length, char *in_data);
int set_data(char *data);
void print() {cout＜＜data＜＜endl;}
};
class edit_string: public string
{
int cursor;
public:
int get_cursor() {return cursor;}
void move_cursor(int dis) {cursor=dis;}
int add_data(string *new_data);
void delete_data(int num);
};
int string::set_data(int in_length,char *in_data)
{
length=in_length;
if(!data)
delete data;
(1)
strcpy(data,in_data);
return length;
}
int string::set data(char *in_data)
{
(2)
if(!data)
delete data;
(1)
strcpy(data,in_data);
return length;
}
int edit_string::add_data(string *new_data)
{
int n,k,m;
char *cp,*pt;
n=new_data-＞get_length();
pt=new_data-＞get_data();
cp=this-＞get_data();
m=this-＞get_length();
char *news=new char[n+m+1];
for(int i=0; i＜cursor; i++)
news[i]=cp[i];
k=i;
for(int j=0; j＜n; i++,j++)
news[i]=pt[j];
cursor=i;
for(j=k; j＜m; j++,i++)
(3)
news[i]='\0';
