What does this mean?

**jw232** · 05-14-2008

Code:

struct myclass {
  bool operator() (int i,int j) { return (i<j);}
} myobject;

I saw this while browsing a C++ reference. I don't understand what myobject is when it's between the } and ;

It defines an instance of class myclass with the name myobject.
It's the same as

Code:

struct myclass {
  bool operator() (int i,int j) { return (i<j);}
};
myclass myobject;

Err, right. My bad >_<

Code:

struct {
  bool operator() (int i,int j) { return (i<j);}
} isSmaller;

int x=10, y=20;
isSmaller(x, y);

now it makes more sense!

..rather an instance of struct myclass

..which in the context of C++, thus a C++ struct, is the same as a class except that in structs all members default to public.
