有如下程序:#includeiostreamusingnamespacestd;classTest{public:Test(){n+=2;}~Test(){n-=3;}staticintgetNum(){returnn;}private:staticintn;};intTest::n=1;intmain(){Test*p=neWTest;deletep;coutn=Test::getNum()endl;return0;}执行该程序的输出结果是( )。A.n=0B.n=1C.n=2D.n=3

有如下程序:

#include<iostream>

usingnamespacestd;

classTest

{

public:

Test(){n+=2;}

~Test(){n-=3;}

staticintgetNum(){returnn;}

private:

staticintn;

};

intTest::n=1;

intmain()

{

Test*p=neWTest;

deletep;

cout<<"n="<<Test::getNum()<<endl;

return0;

}

执行该程序的输出结果是( )。

A.n=0

B.n=1

C.n=2

D.n=3
