Answer 1

What rules do you use to name your variables?

• I need to be able to understand it in a year's time. Should also conform with preexisting style.

Where are single letter vars allows?

• ultra-obvious things. E.g. char c; c = getc(); Loop indicies(i,j,k).

How much info do you put in the name?

• Plenty and lots.

how about for example code?

• Same as above.

what are your preferred meaningless variable names? (after foo & bar)

• I don't like having meaningless variable names. If a variable doesn't mean anything, why is it in my code?

why are they spelled "foo" and "bar" rather than FUBAR

• Tradition.
