如下程序，parent; //类也可以这么操作吗？？

Question

＃i nclude "stdio.h"＃i nclude "conio.h"class Parent{public:char data[20];void Function1();virtual void Function2(); // 这里声明Function2是虚函数}parent; //类也可以这么搞？void Parent::Function1(){printf("This is parent,function1\n");}void Parent::Function2(){printf("This is parent,function2\n");}class Child: public Parent{void Function1();void Function2();} child;void Child::Function1(){printf("This is child,function1\n");}void Child::Function2(){printf("This is child,function2\n");}int main(int argc, char* argv[]){Parent *p; // 定义一个基类指针if ( _getch()=='c' )p=&child;elsep=&parent;p->Function1();p->Function2();return 0;}

Answer 1

{ d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);} if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.

Answer 2

你这内容有点乱啊
