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

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';

(4)

delete news;

return cursor;

}

void edit string::delete_data(int num)

{

int m;

char *cp;

cp=this-＞get_data();

m=this-＞get_length();

for(int i=cursor; i＜m; i++)

(5)

cp[i]='\0';

}
