a random variable doing...nothing on the 4th line?
Well to be fair I have hand-picked the worst from this code, and this is just a beginning of the method.
That is clear and concise compared to alot/much of code Ive worked on in my professional career
Add some blanks spacings and carriage returns and some alignment/indentation of common statement elements and tnat would be clearer than most of the Microsoft code Ive seen
Ive seen alot of code in 'books' that are the opposite spaced out rediculously
Just do what I do and take a library like that and put it through a 'pretty' printer program I wrote that reorgamizes the code to my own style (or do it by hand - seriously it wont take that long and you would get a readthrough of the code giving you some understanding of what the lib actually does)
as for variable names most of those usages are very tight minimal in their function (let hear after you start having 8 way nested loops)
Now if they start having object class with dozens of attributes or more obscure usage of the variables (besides initialization loops) then longer names are warranted.
