Variation of scanf()

Is it correct to use scanf() as follows:

int n;
scanf("[%d]", &n);

If so, what does it do?

scanf("[%d]", &n);

Will extract the int a a given line if the string is something like:[1234] It will extract the value 1234 and store it in the int.

It reads a square bracket (the [), then a converts a decimal integer and stores the result in n, then reads a closing square bracket. The brackets themselves are simply skipped over, they're not part of the conversion.

You might be thinking of the character group conversion specifier, which looks like %[...], where the ellipsis should be replaced by characters to accept. See the manual page for details.
