Command for inserting for-statement skeleton

Question

How would one write a function that one could bind to, say, SUPER-f, which inserts the code:

for () {
}

in the buffer with my cursor being moved into the () parens for filling out the loop guard?

Didn't try much of anything, since my knowledge of emacs is limited to what's builtin. However, I had not heard of yasnippet and it seems to do the trick. — eof, Feb 28 '16 at 18:35

I think I'd do it like this:

(define-skeleton my-for-statement
  "Insert a for () {...} skeleton."
  nil
  \n "for () {" \n > _ "}" \n)

The \n are for "newlines" (and the ones at beg/end are only added if needed). The _ basically says that if you have selected a region before running the command, then this region will end up right where _ is (IOW, the region will be wrapped by the "for" statement). And the > in front causes this region (if any) to be re-indented.

You can then do M-x my-for-statement and that will insert the statement.
