The 's' replaces a person House match at any given time but the 's+' replaces The full Place sequence directly with the next parameter.
In such cases, it helps make no difference, since you are replacing all the things with the empty string (While it would be far better to employ s+ from an efficiency point of view).

How can it's determined that a prospect has won a condition Although not each of the votes happen to be described?
Utilizing %s in scanf devoid of an explcit area width opens the exact same buffer overflow exploit that gets did; namely, if you will discover much more figures from the enter stream compared to the goal buffer is sized to hold, scanf will happily publish Those people additional characters to memory outdoors the buffer, perhaps clobbering a thing important. Sadly, as opposed to in printf, you can't supply the field with as a operate time argument:
This is often relatively conventional error-checking code for the Python script that accepts command-line arguments.
The primary difference lies in just how it get's managed. When you might have a group of (for instance) three spaces straight following one another s+ normally takes that group and turns The complete it into a "", while s would proces every Place on its own.
And because your second parameter is empty string "", there's no difference between the output of two scenarios.
