Q1: Which of the following is the correct order if calling functions in the below code?
a = f1(23, 14) * f2(12/4) + f3();

ANS:C - Order may vary from compiler to compiler

Here, Multiplication will happen before the addition, but in which order the functions would be called is undefined. In an arithmetic expression the parenthesis tell the compiler which operands go with which operators but do not force the compiler to evaluate everything within the parenthesis first.
