Employing %s in scanf without having an explcit discipline width opens exactly the same buffer overflow exploit that gets did; particularly, if you can find more characters while in the enter stream compared to focus on buffer is sized to carry, scanf will Fortunately write These further figures to memory exterior the buffer, possibly clobbering anything crucial.

What is the origin, precise that means, and intent of labelling the string area "Archi" in an orchestral score?

So if you have a complicated command which you ought to pass to CMD.exe you either have to recollect CMD's argument quoting regulations, and effectively escape each of the quotes, or use /S, which triggers a Specific non-parsing rule of "Strip initially and last " and address all other people as the command to execute unchanged".

This might be more very likely to be appealing during the circumstance during the query Michael Burr linked to, where by cmd.exe is being launched by CreateProcess rather then from a batch file or the command line alone..

Is there some subtlety to /s which is eluding me? When would it ever be Gulf Business Awards important? When would it not even make any difference?
