The main regex will match one whitespace character. The next regex will reluctantly match a number of whitespace figures. For some purposes, both of these regexes are quite comparable, except in the next situation, the regex can match more of your string, if it stops the regex match from failing. from

Working with %s in scanf without an explcit field width opens precisely the same buffer overflow exploit that gets did; specifically, if there are a lot more figures while in the enter stream compared to the concentrate on buffer is sized to hold, scanf will happily publish Those people extra characters to memory outside the buffer, probably clobbering a thing vital. Unfortunately, as opposed to in printf, You cannot provide the field with to be a operate time argument:

Cmd /S is very valuable mainly because it saves you obtaining to bother with "quoting rates". Remember which the /C argument implies "execute this command like I had typed it with the prompt, then Give up".

this assignation can be carried out at initialization like char phrase="this can be a term" // the phrase assortment of chars bought this string now and it is statically described

The width just isn't laid out in the format string, but as yet another integer value argument preceding the argument that should be formatted.

So the initial if assertion translates to: in case you have not passed me an argument, I'm going to tell you how you need to move me an argument in the future, e.g. you'll see this on-screen:

The PEP would not say "supplanted" and in no part of the PEP will it say the % operator is deprecated (however it does say other matters are deprecated down the bottom). You might want str.format and that's great, but right up until there is a PEP stating it is actually deprecated there is no feeling in claiming it can be when it isn't.
