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, sum1, sum2; sum1 = (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?
