Those people two replaceAll calls will always deliver a similar end result, no matter what x is. However, it is important to note which the two normal expressions are not the exact same:
In some code that I've to maintain, I've noticed a structure specifier %*s . Can any person tell me what This is often and why it can be employed?
Working with %s in scanf without having an explcit discipline width opens exactly the same buffer overflow exploit that will get did; particularly, if there are additional people within the input stream when compared to the target buffer is sized to hold, scanf will happily compose People excess people to memory outside the buffer, possibly clobbering anything vital.

this assignation can be carried out at initialization like char phrase="this is a phrase" // the term array of chars obtained this string now and it is statically described
