There's also mixfix where the operators are interleaved between the arguments, of which there are more than two. The well-known one is C's conditional operator:
a ? b : c
This is a single operation `?:` that takes operands a, b, and c.
It's an operator because it's functional (although often with side effects): three expressions go in and one expression goes out.
Control flow constructs deal with statements instead.
