And because your 2nd parameter is vacant string "", there is no difference between the output of two cases.

The width is just not specified in the format string, but as an extra integer value argument preceding the argument that needs to be formatted.

code that have to still pass through a pre-processor. That means it can have #involve and #define amongst other macros. It may additionally be penned as .sx.

All I realize is that cmd.exe's command parsing (In particular with escaping characters) might be strange at times, so I have without a doubt that /s is useful in at least one particular celebration.

Even so x.replaceAll("s+", ""); is going to be additional economical method of trimming spaces (if string may have numerous contiguous spaces) because of potentially significantly less no of replacements because of the to undeniable fact that regex s+ matches one or maybe more spaces directly and replaces them with empty string.

influence of /S is always to override this one exception, so that the two quote figures are still taken out in that circumstance.
