I ask my students to add a 2 letter prefix to variable names in order to keep the different scopes and types of variables sorted out. We don't touch the IFI variables, just the custom code we create...but that helps to identify IFIs code, as well:

First character:
t - type
m -data member of class, struct or
union (non-static)
s - static class scope
g - global scope
a - argument, non-reference
r - reference argument
l - auto local (temporary storage)

Second character:
n - number/scalar, non-enumeration
e - enumeration scalar
s - struct
u - union
a - array
p - pointer

So if we wanted to add a static int "t", it'd be snt and snT. If global, gnt or gnT or if used solely in a function lnt or lnT. It looks a bit awkward, but it really helps me when I'm code reading and debugging.
