How to avoid ambiguous constructors?

[Jason Heyes]

I have a class with two constructors that both take the same type of
argument as a parameter. What should I do to disambiguate my class?

Do you really need all of these constructors?
You can define *pseudo constructors* instead:

class foo { // thanks to Dan W.
private:
// representation
int I;
public:
// constructors
foo(int);
// functions
friend
foo pseudo(int);
};
int main(int argc, char* argv[]) {
foo F(13);
foo G = pseudo(33);
return 0;
}

If you have a good optimizing C++ compiler,
the pseudo constructor won't cost any more
than an actual constructor.
