[TriLUG] names of parameters passed down a chain of functions

[Joseph Mack NA3T]

When I learned programming, I was told that a variable 
should have a different name when it arrives in a function 
(as a parameter). When the new variable is passed to the 
next function, it should have yet another name. It would be 
nice if the names were related, so that the reader would 
connected the various names for the parameters (eg 
image->pixels->my_pixels). However I don't have a sensible 
consistent naming scheme if I do this.

The alternative is to use the same name at all levels and 
let scoping rules handle it for you. This sounds the 
simplest way of handling it.

What do you do?

Thanks Joe
