printf returns the number of bytes written to stdout. "c++" is exactly three bytes long (not counting the null-terminator).
By the way, you really don't need to use the curly braces, you can simply do int i=printf("c" "++");.

@chux, __that's why__ I'm not counting it (there is one in the string itself, but it isn't printed, certainly) – ForceBru Sep 14 '15 at 11:25
