Hi,
I am porting a C++ program to Haskell. My current task is to take a class
hierarchy and produce something equivalent in Haskell, but I don't seem to
be able to get a grip on how type classes and instances contribute to the
solution. Can anyone enlighten me?
Roughly, the class hierarchy in C++ is of the form
class A {
public:
virtual int do_x(int,int) = 0;
};
class B {
public:
int do_x(int x,int y) { ...}
};
class C {
public:
int do_x(int x,int y) { ...}
};
Any help would be greatly appreciated.
Thanks
Simon
