The initial regex will match a person whitespace character. The 2nd regex will reluctantly match one or more whitespace people. For most purposes, these two regexes are extremely identical, besides in the 2nd case, the regex can match more of the string, if it prevents the regex match from failing. from

Using %s in scanf without an explcit field width opens the exact same buffer overflow exploit that receives did; specifically, if there are actually additional figures from the input stream in comparison to the target buffer is sized to hold, scanf will Fortunately produce All those further characters to memory outside the buffer, most likely clobbering one thing critical. However, unlike in printf, You can not supply the field with as being a run time argument:

All of the examples given beneath use arrays which has not been taught but, so I'm assuming I am unable to use %s still possibly.

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

The width is not specified in the structure string, but as yet another integer benefit argument preceding the argument that has to be formatted.

People two replaceAll phone calls will often produce the same final result, in spite of what x is. Even so, it is important to note that the two frequent expressions are usually not exactly the same:

If the value is larger than four character positions wide, the field width expands to accommodate the suitable quantity of figures.

@MichaelBurr: I am fairly absolutely sure he just required the extra set of quotes; the /s was redundant In cases like this, since the problems below which /s tends to make a variation were not satisfied.

and so these information will not be similar to C code documents. Notice that C files can be inlined with assembly Recommendations.

The width is not laid out in the structure string, but as an additional integer worth argument previous the argument that should be formatted.

code that need to continue to go through a pre-processor. Which means it can have #include things like and #define amongst other macros. It may also be published as .sx.

Is there more info some subtlety to /s which is eluding me? When wouldn't it ever be important? When would it even make any variation?
