I have two object type that I wanted to compare to each other using the
operator=3D=3D but to my surprise, which I compiled it, I got a complaint
about the different types being used without cast
euler.cpp|113 col 28| error: comparison between distinct pointer types
=E2=80=98tree::Predicate*=E2=80=99 and =E2=80=98tree::Node*=
=E2=80=99 lacks a cast
my overload operator knows this already
class Predicate{
public:
Predicate(Node& in_a, Node& in_b,
Edge& in_c)
: a{in_a}, b{in_b}, c{in_c}{
a.data++;
b.data++;
};
...
bool operator=3D=3D(const Node& first)
Can anyone suggest the cleanest means of working around this annoying error.
