Re: [suse-programming-e] STL vector as a function parameter with default value (heres another one for you Jerry...)
I've never used that syntax before, could you explain a little? B-) On Friday 11 February 2005 01:25 pm, Davi de Castro Reis wrote:

I would go with two func signatures.
func() { vector<uint> a; this->func(a); } func(vector<uint> &foo) {...}
But probably there is an even better way.

I think that Davi's solution is relatively portable. In C++, you can have
multiple signatures:
1. func() -- Empty parameter list. It simply defines the vector and then
calls the other function in the same class. Probably does not need to use
this->.
2. func(vector<uint> &foo) -- This is the function that does something with
the vector. Because you are calling by reference, I think you must have a
vector to reference. Borland may have some non-standard extensions where
GCC tends to be a crybaby sometimes.
In this case, your code would probably be more portable. You might also want
to make func() inline.

Makes sense once you explain it I saw the {...} and thought he was using something to do with C++ capabilities to unlimited (not really) number of paramters. I was thinking too complicatedly. hehehehe duh! simply overloading. sheesh got it! don't know that that is any cleaner than just having a global empty vetor except I suppose someone could actually use it or assign some values or something, where with the overload, it couldn't happen.

simply overloading. sheesh Think simple. Most programming problems I've faced can be simplified.
