已知:class A{public:int a;int b();int f();int f(int);int g();};class B{public:char f();int g();private:int a;int b();};class C:public A,public B{};设有:C *pc;则:
已知定义public class Employee public class Manager extends Employee public class Contr已知定义public class Employee public class Manager extends Employee public class Contractor extends Employee Employee e=new Employee()
对于类定义:class A{public:virtual void func1(){}void func2(){}};class B:public A{public:
14、关于以下C代码的说法正确的是 public abstract class Animal { public abstract void Eat(); } public class Tiger : Animal { public override void Eat() { Console.WriteLine("老虎吃..."); } } public class Tigress : Tiger { static void Main() { Tigress tiger = new Tigress(); tiger.Eat(); } }
某 Java源文件代码如下: public class A { int a; } class B { int b; } class C { public static void main()
3、下面程序段中,说法正确的是() class location{ public : int GetX(); }; class rectangle:private location { public: int GetW(); };
