4.使用VC6打开考生文件夹下的工程test14_3,此工程包含一个test14_3.cpp,其中定义了类File,但类的定义并不完整。请按要求完成下列操作,将程序补充完整。(1)完成构造函数的定义,使数据成员filename,content指向为空。请在注释“//**1**”之后添加适当的语句;(2)完成函数set_contents的定义,该函数为content申请新的空间来存储new_content的内容,成功返回true,失败返回false。请在注释“//**2**”之后添加适当的语句;(3)完成成员函数copy(File & source,File & target)的定义,该函数实现将source的内容拷贝至target的功能,注意必须使用已经定义的成员函数来实现。请在注释“//**3**”之后添加适当的语句:(4)完成析构函数的定义,要求释放content指向的空间。请在注释“//**4**”之后添加适当的语句。输出结果如下:file2:file1 contentsfile2:file2 contents注意:除在指定的位置添加语句外,请不要改动程序中的其他语句。源程序文件testl4—3.cpp清单如下:include<iostream.h>include<string.h>class File{private:char file_name[64];char*contents;public:File(char*filename){// ** 1 **};File::~File(){// ** 4 **}void printfile(){cout<<file_name<<":"<<contents<<endl;)friend bool copy(File & source,File & target);bool set_contents(char * new_contents);};bool File::set_contents(char*new_contents){// ** 2 **if(contents==NULL)return false;strcpy(contents,new_contents);return true;}bool copy(File & source,File & target){// ** 3 **}void main{){File f1("filel"),f2("file2");f1.set_contents("filel contents");copy(f1,f2);f2.printfile();f2.set_contents("file2 contents,);f2.printfile();}
