第8题：

有如下程序: include using namespace std; class Test{ public: Tes

有如下程序： #include＜iostream＞ using namespace std； class Test{ public： Test() {n+=2;} ～Test() {n-=3;} static int getNum(){return n;} private： static int n; }； int Test::n=1; int main() { Test*p=new Test； delete p； cout＜＜"n="＜＜Test::getNum()＜＜endl； return 0； } 执行后的输出结果是( )。

A．n=0

B．n=1

C．n=2

D．n=3


正确答案：A
解析：语句Test*p=new　Test；会调用类的构造函数Test()　{n+=2;}，使n的值由原来的1变为3，然后delete　p调用类的析构函数～Test()　{n-=3;}，因为n是static型变量，所以会在3的基础上减　3，使得输出结果为0。
