All those two replaceAll calls will always develop a similar consequence, no matter what x is. However, it's important to note which the two typical expressions are not the exact same:

In a few code that I've to keep up, I've witnessed a format specifier %*s . Can any individual explain to me what This really is and why it is applied?

Using %s in scanf with no an explcit field width opens precisely the same buffer overflow exploit that receives did; namely, if you will discover much more figures from the enter stream than the goal buffer is sized to carry, scanf will Fortunately write Individuals added people to memory outdoors the buffer, most likely clobbering some thing crucial.

Every one of the illustrations specified below use arrays which hasn't been taught but, so I'm assuming I can't use %s but both.

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 phrase" // the word variety of chars bought this string now which is statically defined

First off you must recognize that last output of both equally the statements will probably be very same i.e. to eliminate all the spaces from provided string.
