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 ________.
