private int Recursive(int a)
{
a *= 2;
if (a < 1000)

// What should I return here, and why is it needed?
}
else

return a;
}
}
Return value for recursive functions not needed but compiler won't accept.

If I have a simple recursive function:
Why do I need a return value underneath the recursive function call; it will never be reached?
Uh, are you sure you don't mean:
private int Recursive(int a){ a *= 2; if (a < 1000) { return Recursive(a); } else { return a; }}private int Recursive(int a){ return (a >= 1000) ? a : Recursive(2 * a);}This gives different result when a is already >= 1000 at the beginning however ;)
