In my classes I often write a quick operator!=
by returning !(*this == rhs)
, e.g.:
class Foo
{
private:
int n_;
std::string str_;
public:
...
bool operator==(const Foo& rhs) const
{
return n_ == rhs.n_ && str_ == rhs.str_;
}
bool operator!=(const Foo& rhs) const
{
return !(*this == rhs);
}
};
I can't see any obvious problems with doing this but thought I'd ask if anyone knows of any.
