In certain code that I have to take care of, I have seen a structure specifier %*s . Can anyone tell me what This is often and why it can be utilised?

Using %s in scanf devoid of an explcit discipline width opens the same buffer overflow exploit that gets did; particularly, if there are far more people in the input stream in comparison to the concentrate on buffer is sized to carry, scanf will Fortunately create All those excess characters to memory outside the buffer, probably clobbering a thing important. Sadly, not like in printf, You cannot provide the sector with being a run time argument:

The explanation driving the code if I am using %s as an alternative to %c in my printf portion in the code 82

The main difference lies in the way in which it get's dealt with. Should you would have a gaggle of (such as) three spaces directly next one another s+ normally takes that group and turns The complete it into a "", while s would proces every House on its own.

Observe also that i'm using a tuple listed here in addition (once you have only a person string using a tuple is optional) As an example that multiple strings could be inserted and formatted in a single assertion.

The width is just not specified in the structure string, but as yet another integer price argument preceding the argument that should be formatted.

this assignation can be achieved check here at initialization like char word="that is a word" // the phrase assortment of chars obtained this string now and it is statically described

To start with you need to realize that remaining output of each the statements might be exact same i.e. to get rid of many of the Areas from offered string.

So the main if assertion interprets to: when you have not passed me an argument, I'm going to tell you how you need to pass me an argument in the future, e.g. you will see this on-display screen:
