下面这个程序的结果是 #include＜iostream.h＞ class A { private:int a; public: void seta( ) ;int geta( ) ;}; void A: :seta( ) { a＝1;} int A: :geta( ) { retum a;} class B { private:int a; public:void seta( ) ;int geta( ) ;}; void B: :seta( ) {a＝2;} int B: :geta( ) {return a;} class C: public A，public B { private:int b; public:void display( ) ;}; void C: :display( ) { int b＝geta( ) ; cout ＜ ＜ b;} void main( ) { C c; c. seta( ) ; c. display( ) ;} Ａ) 1 Ｂ) 2 Ｃ) 随机输出1或2 Ｄ) 程序有错
