Let the function fun be defined as int fun (int*k) { *k += 4; return 3 * (*k) 1; } Suppose fun is used in a program as follows: void main() { int i = 10, j 10, sumi, sum2; suml = (i / 2) + fun (&i); sum2 = fun (&j) + (j / 2); } What are the values of sum1 and sum2 a. operands in the expressions are evaluated left to right? b. operands in the expressions are evaluated right to left
