Q8.
Consider the C program below. #include < stdio.h > int *A, stkTop; int stkFunc(int opcode, int val) { static int size=0, stkTop=0; switch (opcode) { case -1: size = val; break; case 0: if (stkTop < size) A[stkTop++] = val; break; default: if (stkTop) return A[--stkTop]; } return -1; } int main() { int B[20]; A = B; stkTop = -1; stkFunc (-1, 10); stkFunc ( 0, 5); stkFunc ( 0, 10); printf ("%d\n", stkFunc(1, 0) + stkFunc(1, 0)); } The value printed by the above program is __________.
