5. (6pts) Let the function fun be defined as: int fun(int "k) ( "k += 4; return 3 * (%)-1 ; Suppose fun was used in a program as follows: void main(){ int i= 10, j = 10, sumi, sum2; sum1 = (i / 2) + fun(&i); sum2 = fun(8)) + ( j / 2); What are the values of sum1 and sum:2 a) If the operands in the expressions are valuated left to right? b) if the operands in the expressions are evaluated right to left
