No, there’s no such guarantee. It’s unspecified according to the C++ standard.
Bjarne Stroustrup also says it explicitly in “The C++ Programming Language” 3rd edition section 6.2.2, with some reasoning:
Better code can be generated in the
absence of restrictions on expression
evaluation order
Although technically this refers to an earlier part of the same section which says that the order of evaluation of parts of an expression is also unspecified, i.e.
int x = f(2) + g(3); // unspecified whether f() or g() is called first
