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()；}
