I see some codings that use:
motors instead of motors …what does "" do , is it for some purpose? I tried searching, but didn’t really have a term to search for…I only see this used once in a while, perhaps it has some significance.
That’s just a naming convention. I use the underscore myself to denote top level private variables that are use inside the class. Others use m at the start of the variable. All just a matter of preference really as long as the code is readable.
I use m_ which I’ve been told is a C++ convention, even though I was doing it long before I ever wrote any C++ code.
When I went to .NET training, the convention that was taught there was to use the underscore “" or "m” for the private fields in a class, and to drop those prefixes for the public accessors to those fields.
Nice brief doc on one of the used naming conventions:

I agree with Architect’s link. I’ve been doing this for a long time, 30+ years, and naming conventions that use Hungarian notation or prefix with underscores just seem old fashioned to me 
Well, they ARE old fashioned. It’s taken me long enough to stop using lots_of_underscores_in_method_and_variable_names (from my early learning days in C) so I figure I can keep my m_ for a good while yet
Our company went through a phase of putting the scope and type in the variable name:
So I guess it was Hungarian + notation.
(this was from the VB6 days)
miValue = module integer
liValue = local integer
cmiValue = constant module integer
blech … glad that was a quick phase!
