The 's' replaces one particular Place match at any given time although the 's+' replaces The full Place sequence directly with the next parameter.
In such a case, it can make no difference, since you are replacing all the things with the empty string (Though It could be better to work with s+ from an performance standpoint). In the event you have been replacing that has a non-vacant string, The 2 would behave otherwise. Share Improve this solution Stick to
How can or not it's decided that a applicant has received a state While not each of the votes are actually documented?
Using %s in scanf with no an explcit industry width opens precisely the same buffer overflow exploit that receives did; specifically, if you'll find extra people inside the input stream than the goal buffer is sized to hold, scanf will happily publish Those people extra characters to memory outside the buffer, probably clobbering anything significant. Regretably, unlike in printf, you can't source the sphere with to be a operate time argument:
That is fairly common mistake-examining code to get a Python script that accepts command-line arguments.
The primary difference lies in just how it get's taken care of. When you might have a group of (for instance) three Areas immediately pursuing each other s+ requires that team and turns The full it into a "", though s would proces each individual Room on its own.
And since your 2nd parameter is empty string "", there isn't a distinction between the output of two cases.

The width is just not specified in the structure string, but as a further integer worth argument preceding the argument that should be formatted.
this assignation can be achieved at initialization like char term="it is a term" // the word assortment of chars received this string now and is particularly statically defined
If the worth is greater than 4 character positions huge, the field width expands to accommodate the suitable number of characters.
