Warning about hiding member variables?

Question

The following code snippet has a memory leak that I spent too much time chasing down. The problem is that inside Foo(), the local variable x_ hides the member variable x_.

Answer 1

We use these warts on the beginnings of names - a_ argument d_ data member s_ static data in class f_ static data in file

... and no wart for local variables.
