Not true.

You passed NULL to GetMemory. That NULL was copied into p (that's what pass by value does). You then changed p's value to the result of the memory allocation and altered that memory block.

So, in effect, you passed a reference to the memory starting at NULL, then threw away that reference in GetMemory by doing

p =  new char[100];

We believe str is still NULL, where I have mistaken?


No mistake, str will remain NULL with your code. Did you look at the code samples I provided you?

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
