Order of evaluation in C++ function parameters

Question

If we have three functions (foo, bar, and baz) that are composed like so...

foo(bar(), baz())

Is there any guarantee by the C++ standard th

Answer 1

There's no specified order for bar() and baz() - the only thing the Standard says is that they will both be evaluated before foo() is called. From the C++ Standard, section 5.2.2/8:

The order of evaluation of arguments is unspecified.
