( 31 )有如下程序

#include <iostream>

using namespace std;

Class Base{

public:

Base(int x=0):valB(x) {cout<<valB;}

~Base() {cout<<valB;}

private:

int valB;

};

class Derived:public Base{

public:

Derived(int x=0,int y=0):Base(x),valD(y){cout<<valD;}

~Derived() {cout<<valD; }

private:

int valD;

};

int main(){

Derived obj12(2,3);

retuen 0;

}

运行时的输出结果是

A ) 2332

B ) 2323

C ) 3232

D ) 3223
