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.

However x.replaceAll("s+", ""); will likely be a lot more successful strategy for trimming spaces (if string can have numerous contiguous Areas) because of probably fewer no of replacements thanks the to proven fact that regex s+ matches one or even more spaces at the same time and replaces them with vacant string.

so "indent" specifies exactly how much Place to allocate for that string that follows it while in the parameter list.

Using %s in scanf with no an explcit field width opens the exact same buffer overflow exploit that receives did; namely, if you will discover extra characters while in the enter stream compared to goal buffer is sized to hold, scanf will Fortunately create Individuals excess figures to memory exterior the buffer, probably clobbering something important. Regrettably, contrary to in printf, You cannot offer the sector with like a operate time argument:

This is certainly rather regular mistake-checking code for just a Python script that accepts command-line arguments.

The main difference lies in just how it get's dealt with. Should you might have a gaggle of (as an example) 3 Areas instantly adhering to one another s+ can take that group and turns the whole it right into a "", although s would proces each and every space By itself.

 

The %s token makes it possible for me to insert (and possibly format) a string. Notice the %s token is replaced by what ever I pass on the string once the % image.

The PEP doesn't say "supplanted" As well as in no A part of the PEP does it say the % operator is deprecated (however it does say other issues are deprecated down The underside). You could possibly choose str.format and that's wonderful, but until finally there is a PEP stating it can be deprecated there here is not any sense in boasting it is when it's not.

Each of the examples specified beneath use arrays which has not been taught yet, so I'm assuming I am unable to use %s nonetheless possibly.

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

this assignation can be carried out at initialization like char word="this is the word" // the phrase assortment of chars acquired this string now and it is statically outlined

To start with you need to realize that closing output of each the statements might be exact same i.e. to get rid of the many Areas from given string.
