The 's' replaces one particular Place match at any given time although the 's+' replaces The complete Place sequence directly with the next parameter.
In such a case, it helps make no change, since you are replacing anything with an empty string (While it would be far better to implement s+ from an performance point of view). Should you ended up changing which has a non-vacant string, The 2 would behave in a different way. Share Increase this remedy Stick to
How can it's made the decision that a prospect has won a condition Although not the many votes have already been claimed?
Employing %s in scanf without an explcit discipline width opens the same buffer overflow exploit that will get did; particularly, if there are a lot more figures during the enter stream compared to focus on buffer is sized to carry, scanf will Fortunately produce those added figures to memory outdoors the buffer, most likely clobbering a little something essential. However, compared with in printf, You can not offer the sector with being a run time argument:
That is fairly common mistake-examining code for any Python script that accepts command-line arguments.
The primary difference lies in just how it get's managed. When you might have a bunch of (as an example) 3 Areas right adhering to each other s+ usually takes that group and turns the whole it right into a "", even though s would proces each and every space By itself.

And because your 2nd parameter is empty string "", there isn't a distinction between the output of two scenarios.

The width is not really laid out in the format string, but as an additional integer benefit argument previous the argument that must be formatted.
this assignation can be done at initialization like char phrase="this can be a term" // the word variety of chars got this string now which is statically defined
Firstly you have to know that remaining output of the two the statements are going to be exact same i.e. to get rid of the many Areas from offered string.
