Hi, i have seen a few ways to get the number of elements in an array but i couldn't make it work while calling it inside a method of a class.


CWeb::CWeb(std::string data, CWeb *Webs)
{
//Code to add all of the Webs into a linked list inside CWeb
//Webs is a pointer to an array of CWeb type objects
}

So basicaly i need to be able to know the number of elements inside Webs in this function. Any ideas? (Passing the number of Webs as another parameter is not acceptable). THanks

From an arbitrary bare pointer there is no method to get the size of an array. If passing the number of elements is unacceptable, consider passing a pointer or reference to a container class of CWeb rather than a pointer to CWeb.

I have seen methods with templates that work while you are not inside a class, there must be a method.
