naming convention of temp local variables

Question

What is the standard way to name a temp variable in the local function? let me give you an illustration of what I am doing. I get a pointer to a structure, so I want store one o

Answer 1

In general, I just use descriptive names. If it's an attribute, I make the first letter uppercase and apply camel-casing. For local variables, I keep everything lowercase. For variables that store attribute names, I use lower-case with an underscore as prefix. I avoid using any shorthand notations and generally don't need shorthand either. Code Completion is very useful with long names. :-)

Several IDE's will use Code Highlighting which is practical if you need to know if something is a class or variable. Thus I don't make many differences between class names and attribute names. (Except in Delphi, where I still prefix every class with a T since that's a standard convention in Delphi.)

And no, I don't use tmp. I write it out as Temporary, just in case I can't come up with a different name. Or I, J, K, L or M in case of index-numbers. (No, just those 5 letters, always uppercase.) In your case, I'd use "oldvalue" or "oldm_d" instead.
