* Causes fprintf to pad the output right up until it truly is n figures huge, exactly where n can be an integer worth stored inside the a functionality argument just preceding that represented via the modified style.
Even so x.replaceAll("s+", ""); might be extra efficient way of trimming Areas (if string can have a number of contiguous spaces) for the reason that of doubtless fewer no of replacements owing the to fact that regex s+ matches one or even more spaces without delay and replaces them with vacant string.
so "indent" specifies the amount of Room to allocate to the string that follows it within the parameter record.
5 @powersource97, %.*s indicates you are examining the precision worth from an argument, and precision is the most amount of characters to generally be printed, and %*s you happen to be studying the width price from an argument, which can be the minimum variety os people to get printed.

See also that I am utilizing a tuple here at the same time (when you only have one particular string employing a tuple is optional) to illustrate that a number of strings is usually inserted and formatted in one statement.
The width isn't laid out in the structure string, but as an extra integer value argument previous the argument that needs to be formatted.
If the worth here being output is below 4 character positions huge, the value is true justified in the field by default.
If the value is bigger than four character positions vast, the sphere width expands to accommodate the suitable range of characters.
So the initial if statement translates to: in the event you haven't handed me an argument, I'll inform you how it is best to move me an argument Later on, e.g. you'll see this on-screen:
