* Will cause fprintf to pad the output right until it is actually n people extensive, the place n is really an integer worth saved from the a operate argument just preceding that represented via the modified form.
In cases like this, it makes no variance, because you are changing every little thing having an vacant string (Though It could be better to utilize s+ from an effectiveness viewpoint). If you had been replacing by using a non-empty string, the two would behave in different ways. Share Make improvements to this answer Adhere to
In some code that I've to maintain, I've observed a structure specifier %*s . Can any individual inform me what this is and why it is actually utilised?
Applying %s in scanf without having an explcit industry width opens the identical buffer overflow exploit that receives did; specifically, if you'll find additional people within the input stream in comparison to the target buffer is sized to carry, scanf will Fortunately create People excess people to memory outside the house the buffer, potentially clobbering one thing critical. Sad to say, unlike in printf, You can not source the sphere with for a operate time argument:
This is often relatively conventional error-checking code for your Python script that accepts command-line arguments.
The difference lies in the way it get's taken care of. If you would've a bunch of (as an example) 3 Areas immediately subsequent one another s+ requires that team and turns The entire it right into a "", when s would proces each individual Place on its own.
And since your next parameter is vacant string "", there is no difference between the output of two conditions.
