什么是间接转述句Point& operator ++();
Point operator ++(int);
Point& operator --();
Point operator --(int);临汾牛肉丸子面
friend ostream& operator <<(ostream& out,Point& a);

_x++;
_y++;
return *this;
}
Point Point::operator++(int)
直为斩楼兰{
Point old=*this;

{
_x--;

return *this;
}
Point Point::operator --(int)

极其的近义词}

{
out<<"("<<a._x<<","<<a._y<<")";
return out;
}
化学会int main()

a++;
cout<<a<<endl;
