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));
}
#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:

{
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 ___________
- a)15
- b)10
- c)27
- d)9
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Consider the C program below.#include <stdio.h>int *A, stkTop;in...
The code in main, basically initializes a stack of size 10, then pushes 5, then pushes 10.
Finally the printf statement prints sum of two pop operations which is 10 + 5 = 15.
stkFunc (-1, 10); // Initialize size as 10 stkFunc (0, 5); // push 5
stkFunc (0, 10); // push 10
// print sum of two pop
printf ("%d\n", stkFunc(1, 0) + stkFunc(1, 0));
stkFunc (0, 10); // push 10
// print sum of two pop
printf ("%d\n", stkFunc(1, 0) + stkFunc(1, 0));

Understanding the Program
This C program implements a simple stack using a static array and a stack function. Here's a breakdown of its key components:
Global Variables
- `int *A, stkTop;` declares a pointer `A` that will point to an array and an integer `stkTop` to track the stack index.
Stack Function Logic
- The `stkFunc` function has three operations based on the `opcode`:
- -1: Initializes the stack size (`size`) to `val`.
- 0: Pushes `val` onto the stack if there's space.
- Default: Pops the top value from the stack if it's not empty.
Function Execution Steps
1. Initialization (`main`):
- `int B[20];` creates an array `B` of size 20.
- `A=B;` makes `A` point to the array `B`.
- `stkTop = -1;` sets the stack top to -1 (empty stack).
2. Set Stack Size:
- `stkFunc (-1, 10);` sets the stack size to 10.
3. Push Values:
- `stkFunc (0, 5);` pushes 5 onto the stack.
- `stkFunc (0, 10);` pushes 10 onto the stack.
Final Calculations
- The two calls to `stkFunc(1, 0)` pop values from the stack:
- First call: Pops 10 (stkTop becomes 0).
- Second call: Pops 5 (stkTop becomes -1).
- The sum of these two values is `10 + 5 = 15`.
Final Output
- The program prints `15`, confirming that the correct answer is option A.
