What is vim syntax name for printf placement %d within strings?

Within printf format strings, the placement characters, from % to the corresponding d, or x appear in dark blue. With a black background, they are very hard to read.

To change the color, I 开发者_Python百科know I have to change the color with a command like this:

highlight Comment ctermfg=Cyan

But I have to put the correct syntax group name instead of Comment.

Does anyone know what this syntax group name is?

It's cFormat. You can check what group is under the cursor by executing:

:echo synIDattr(synID(line("."),col("."),1),"name")

That group's name is cFormat.
