( 33 )下面程序中对一维坐标点类 Point 进行运算符重载
#include
using namespace std;
class point {
public:
point ( int vaI ) {x=val;}
point & operator++ () {x++;retum*this;}
print operator++ ( int ) {point ld=*this,++ ( *this ) ;retum old;}
int GetX () const {retum x;}
private:
int x;
};
int main ()
{
point a ( 10 ) ;
cout$amp;cout$amp;retum () ;
}
编译和运行情况是
A )运行时输出 1011
B )运行时输出 1111
C )运行时输出 1112
D )编译有错
