The 's' replaces one particular Place match at any given time though the 's+' replaces The complete House sequence without delay with the 2nd parameter.
In this case, it would make no distinction, since you are changing everything using an vacant string (although It might be superior to make use of s+ from an effectiveness viewpoint). For those who had been replacing using a non-empty string, the two would behave otherwise. Share Make improvements to this solution Stick to
so "indent" specifies the amount Room to allocate for your string that follows it within the parameter record.
Employing %s in scanf without an explcit subject width opens the same buffer overflow exploit that will get did; particularly, if there are a lot more figures during the input stream compared to focus on buffer is sized to carry, scanf will Fortunately generate These further figures to memory exterior the buffer, likely clobbering something crucial. However, contrary to in printf, You can not offer the sector with being a run time argument:
The rationalization powering the code if i'm using %s as an alternative to %c in my printf section in the code 82
Applying scanf Along with the %s conversion specifier will end 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 must be formatted.
char character; // only a char 1 letter/through the ascii map character = 'a'; // assign 'a' to character
The PEP will not say "supplanted" As well as in no Section of the PEP does it say the % operator is deprecated (nonetheless it does say other factors are deprecated down the bottom). You may here perhaps desire str.structure and that's great, but right up until there's a PEP declaring it's deprecated there isn't any perception in professing it is when it is not.

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 carried out at initialization like char word="this is the word" // the term array of chars obtained this string now and it is statically outlined
This way it could stand By itself. Supplying an instance that was akin to the example from the dilemma would even be a moreover.
