有如下程序:includeusing namespace std;class Base{int x;public:Base(int n=0):x(n 有如下程序: #include<iostream> using namespace std; class Base{ int x; public: Base(int n=0):x(n){cout<<n;} int getX( )const{return x;} }; class Derived:public Base{ int y; public: Derived(int m,int n):y(m),Base(n){tout<<m;} Derived(int m):y(m){cout<<m;} }; int main( ){ Derived dl(3),d2(5,7); return 0; } 程序的输出结果是A.375B.357C.0375D.0357

下列程序中说明的公有成员是( ) 。class Location { int X; public: void init(int initX,int initY); private: int Y; public: int GetX(); int GetY(); }; A.init(int initX,int initY)B.XC.GetX(),GetY()D.B和C都是

指出下面程序段中的错误,并说明出错原因【 】。class Location {int X, Y=20;protected:int zeroX, zeroY;int SetZero(int ZeroX, iht ZeroY);private:int length, height;public:float radius;void init(int initX,int initY);int GetX();Int GetY();};

有以下程序: include using namespace std; class Point' { public: void SetPoint( 有以下程序: #include <iostream> using namespace std; class Point' { public: void SetPoint(int x,int y); void Move(int xOff,int yOff); int GetX() { return X; } int GetY() { return Y; } private: int X,Y; }; void Point::SetPoint(int x, int y) { X=x; Y=y; } void Point: :Move(int xOff, int yOff) X+=xOff; Y+=yOff; } int main () { Point p1; p1.SetPoint(1,2); p1.Move (5, 6); cout<<"Point1 is ("<<p1.GetX()<<','<<p1.GetY()<<")"<<end1; return 0; } 执行后的输出结果是( )。A.Point1 is (6,8)B.Point1 is (1,2)C.Point1 is (5,6)D.Point1 is (4,4)

执行下列代码后,输出的结果为( )。 class Base { int x = 30; void setX( ) {x=1O;} } class SubClass extends Base { int x=40; void setX ( ) {x=20;} int getX( ) {return super. x; } } public class Test { public static void main(String[ ] args) { SubClass sub=new SubClass( ); sub. setX( ); System. out. println(sub, getX( ) ); } }A.10B.20C.30D.40

类A定义如下: class A { private int x=10; int getx() { return x;} } class B extends A { private int x=15; //需要覆盖getx()方法 } 在下述方法中可以在类B中覆盖getx()方法的是 ( )A.int getx(){…}B.int getx(float f){…}C.float getx(){…}D.double getx(float f){…}

有如下类定义: class Test { private int x; public int y; public void setX (int m) {x=m;} public int getX( ) {return x;} }现用Test t=new Text();生成一个对象t,则如下语句中,错误的是( )。A.t.x=10;B.t.y=10;C.t. setX(10);D.int m=t.getX( );

根据注释内容在空白处填写适当内容。class Location{private:int X,Y;public:void init(int initX,int initY);int GetX( );int GetY( );};void Location::init(int initX,int initY){X=initX;Y=initY;}int Location::GetX( ){reutrn X;}int Location::GetY( ){reutrn Y;}include<iostream.h>void main( ){Location A1;A1.init(20,90);______ //定义一个指向A1的引用rA1cout<<rAl.GetX( )<<":"<<rAl.GetY( )<<endl;}
