Answer / james holdcroft

The output will be 1 or 3, depending on the compiler.

Quoting from "The C Programming Language, Second Edition"
by Kernighan and Ritchie:

C, like most languages, does not specify the order in which
operands of an operator are evaluated. (The exceptions are
&&, ||, ?:, and ','.)
...
One unhappy situation is typified by the statement
a[i] = i++;
The question is whether the subscript is the old value of i
or the new. Compilers can interpret this in different
ways, and generate different answers depending on their
interpretation.
