The 's' replaces 1 Area match at a time though the 's+' replaces the whole House sequence at once with the 2nd parameter.

In this instance, it will 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). For those who had been replacing using a non-empty string, the two would behave in different ways. Share Make improvements to this answer Stick to

In some code that I have to maintain, I've noticed a structure specifier %*s . Can any person inform me what this is and why it can be utilised?

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 characters 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 little something essential. Regrettably, contrary to in printf, You cannot offer the sector with being a run time argument:

The explanation driving the code if I am using %s as an alternative to %c in my printf portion from the code 82

Working with scanf Together with the %s conversion specifier will cease scanning at the very first whitespace character; for example, In the event your input stream appears like

The width is just not laid out in the format string, but as a further integer benefit argument preceding the argument that needs to be formatted.

char character; // only a char 1 letter/with the ascii map character = 'a'; // assign 'a' to character

The PEP does not say "supplanted" As well as in no Portion of the PEP will it say the % operator is deprecated (nevertheless it does say other items are deprecated down The underside). You would possibly choose str.structure and that's high-quality, but right up until there is a PEP declaring it is deprecated there isn't any perception in professing it is when it is website not.

All of the examples supplied below use arrays which hasn't been taught however, so I'm assuming I can't use %s but both.

The width isn't laid out in the structure string, but as an extra integer value argument previous the argument that needs to be formatted.

this assignation can be achieved at initialization like char term="that is a word" // the phrase assortment of chars acquired this string now and is statically outlined

To begin with you'll want to understand that closing output of both the statements is going to be same i.e. to remove every one of the Areas from given string.
