Question

C++面向对象部分中多重继承中的默认构造函数怎么写 就如这个题，哪儿错了啊

#include <iostream.h>
class A
{
int a,b;
public:
A(){a=1;b=2;}
int geta(){return a;}
int getb(){return b;}
};
class B
{
int x,y;
public:
B(){x=3;y=4;}
int getx(){return x;}
int gety(){return y;}
};
class AB:public A,public B
{
public:
AB():A():B(){}
};
void main()
{
AB obj;
cout<<obj.getx()<<endl;
}

Answer 1

AB():A(),B(){}
两个父类构造函数名之间应该是逗号，这样试试看
