c++ - Order of function calling

Question

What will be the order the function calls in the following expression:

a = f1(23, 14) * f2(12/4) + f3();

Does it depend on the compiler?

Answer 1

Order of evaluation of each operand is unspecified in C and C++, which means, in your case, the order of function calling is unspecified as per the Standards.

Note that it is unspecified, not implementation-defined.
