若有以下程序： #include ＜iostream＞ using namespace std; class Base { private:int x; protected:int y; public:int z;void setx(int i){ x=i;int getx (){ return x;} }; class Inherit : private Base { private:int m; public:int p;void setvalue(int a, int b, intc, int d){ setx (A) ; y=b; z=c; m=d;}void display(){ cout＜＜getx () ＜＜","＜＜y＜＜","＜＜z＜＜","＜＜m＜＜end1;} }; int main ( ) {Inherit A;A.setvalue(1,2,3,4);A.display ();return 0; }
A．1,2,3,4
B．产生语法错误
C．4,3,2,1
D．2,3,4,5
