The 's' replaces one Area match at a time however the 's+' replaces the whole space sequence at once with the 2nd parameter.
In this instance, it would make no big difference, because you are changing every thing by having an vacant string (Even though It might be improved to make use of s+ from an effectiveness viewpoint). In case you were being changing with a non-empty string, The 2 would behave differently. Share Boost this response Abide by
How can it be made a decision that a candidate has gained a point out Despite the fact that not all of the votes are noted?
Applying %s in scanf without having an explcit industry width opens the identical buffer overflow exploit that receives did; specifically, if you'll find additional people within the input stream when compared to the target buffer is sized to hold, scanf will happily create People additional characters to memory outdoors the buffer, perhaps clobbering a little something important. Regrettably, not like in printf, You cannot provide the field with like a run time argument:
The explanation driving the code if I am using %s as an alternative to %c in my printf section in the code eighty two
Using scanf While using the %s conversion specifier will halt scanning at the primary whitespace character; as an example, if your input stream seems like
The initial a person matches an individual whitespace, Whilst the 2nd a single matches one particular or many whitespaces. They're the so-named regular expression quantifiers, and so they conduct matches similar to this (taken from the documentation):
char character; // only a char 1 letter/with the ascii map character = 'a'; // assign 'a' to character
The PEP would not say "supplanted" and in no A part of the PEP will it say the % operator is deprecated (still it does say other factors are deprecated down The underside). You would possibly choose str.structure and that's great, but right up until there is a PEP declaring it is deprecated there isn't any perception in proclaiming it is actually when it isn't.
