Employing %s in scanf without the need of an explcit industry width opens exactly the same buffer overflow exploit that will get did; namely, if you can find a lot more characters while in the input stream as opposed to target buffer is sized to carry, scanf will Fortunately write Individuals extra people to memory outside the buffer, potentially clobbering one thing significant. Sadly, in contrast to in printf, you can't source the field with being a operate time argument:

If you always use /S, it is possible to ignore the exception and just recall the "regular" scenario. The downside is that cmd.

Home windows, which derives in the long run from CP/M and VAX, won't use This technique internally. For the running technique, the command line is just a single string of people.

The PEP does not say "supplanted" As well as in no Element of the PEP will it say the % operator is deprecated (nonetheless it does say other points are deprecated down the bottom).
