Parameter Passing Example from a Previous Exanm void main() int aM[] = {10, 20, 30} int k = 2; sub(aM[k], k); print ('main', k, aM[0], aM[1], aM[2]); void sub(int x, int y) x += 3; printf('sub', x, y); Trace and show the output produced by the code using the following parameter transmission schemes: a. by value b. by true reference c. by copy-restore reference d. by name Problem a. by value aM 10 20 30 Problem b. by true ref aM 10 20 30 main k 2 k 2 sub Output sub sub main main Problem c. by copy-restore aM 10 20 30 Problem d. by name aM 10 20 30 main k 2 k 2 sub Output sub sub main main
