fmt.Scanf: any way to do something like %*f in C

[朱必胜]

Hi,

I have read the scan.go in go/src, and can't find an easy way to skip a field in the input stream, in C, we have a %*f, with * to skip, how to do that for golang?

There is no way beyond storing into a variable whose value you ignore.

There are two ways to do this without creating a new variable: http://play.golang.org/p/RjPsgsCCfG

But honestly, it makes more sense to simply create the extra variable and ignore it, so that if you ever need the field, or reuse the code, you aren't confused later.

Also method 2 is more brittle to changes in the implementation of scanf.
