The 's' replaces a single Room match at a time nevertheless the 's+' replaces The full Room sequence directly with the next parameter.

Those two replaceAll phone calls will often produce exactly the same result, in spite of what x is. Nonetheless, it is necessary to notice that the two frequent expressions will not be exactly the same:

In certain code that I have to take care of, I have seen a structure specifier %*s . Can anyone convey to me what This is certainly and why it really is utilized?

Making use of %s in scanf without an explcit subject width opens exactly the same buffer overflow exploit that will get did; particularly, if there are far more people in the input stream as opposed to focus on buffer is sized to carry, scanf will Fortunately generate These added 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:

This is certainly relatively conventional error-checking code for just a Python script that accepts command-line arguments.

The real difference lies in how it get's managed. When you might have a group of (for instance) three Areas immediately subsequent one another s+ usually takes that group and turns the whole it right into a "", although s would proces each and every space By itself.

And because your second parameter is empty string "", there is absolutely no distinction between the output of two conditions.

How to proceed with a youngster who's searching for more info focus negatively and now is starting to become agressive towards others?

this assignation can be achieved at initialization like char term="it is a term" // the word variety of chars received this string now and is particularly statically defined

First of all you must recognize that last output of both the statements is going to be same i.e. to remove every one of the Areas from specified string.

So the initial if statement interprets to: if you have not handed me an argument, I will let you know how you must move me an argument Later on, e.g. you'll see this on-monitor:
