写出下面程序的运行结果。 #include using namespace std; class aClass { public: aClass() { total++;} ~aClass() { total--;} int gettotal() { return total;} private: static int total; }; int aClass::total=0; int main() { aClass o1,o2,o3; cout
举一反三
- 读程序,写结果(注意每一空对应一个cout输出结果)#includeusing namespace std;class aClass{public: aClass() { total++; } ~aClass() { total--; } int gettotal() { return total; }private: static int total;};int aClass::total=0;int main(){ aClass o1,o2,o3;cout<
- 读程序,写结果(注意:一条输出语句对应一空)#includeusing namespace std;class aClass{public: aClass() { total++;} ~aClass() { total--;} int gettotal() { return total;}private: static int total;};int aClass::total=0;int main(){ aClass o1,o2,o3;cout<
- 已定义类Aclass:class Aclass {private int x = 1;protected int y = 2;public int z = 3;public int sumA(){ return(x +y +z ); }}再通过继承与扩展定义子类Bclass:class Bclass extends Aclass {private A: s += b; B: s += x; C: s += z; D: s += y;
- 看下面一段程序: class Aclass{ void go(){ System.out.println("Aclass");} } public class Bclass extends Aclass{ void go{ System.out.println("Bclass"); } public static void main(String args[]){ Aclass a=new Aclass(); Aclass a1=new Bclass(); a.go(); a1.go(); } 以上程序运行结果是:(). A: Aclass <br/>Aclass B: Aclass <br/>Bclass C: Bclass <br/>Aclass D: Bclass <br/>Bclass
- 假设Aclass为抽象类,下列正确的说明语句是() A: Aclass fun(int); B: Aclass*p; C: int fun(Aclass); D: AclassObj;
