Consider the C program below.
#include 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 ___________.
- a)5
- b)10
- c)15
- d)20
Correct answer is option 'C'. Can you explain this answer?

Consider the C program below.#include int *A, stkTop;int stkFunc(int o...
The code in main, basically initializes a stack of size 10, then pushes 5, then pushes 10. Finally the printf statement prints the 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));

Understanding the Program Structure
The C program initializes a stack-like structure using a static array. Here's a breakdown of how it operates:
Global Variables
- `int *A, stkTop;` declares a pointer `A` and a variable `stkTop`.
- `A` will point to an integer array `B`, and `stkTop` tracks the current top of the stack.
Function Analysis: stkFunc
- The function `stkFunc` takes two parameters: `opcode` and `val`.
- Opcode -1: Sets the stack size.
- Opcode 0: Pushes `val` onto the stack if there is space.
- Default Case: Pops the top value from the stack if it's not empty.
Execution Flow in main()
1. Initialization:
- An array `B[20]` is created, and `A` points to it.
- `stkTop` is initialized to -1, indicating an empty stack.
2. Setting Stack Size:
- `stkFunc(-1, 10);` sets the stack size to 10.
3. Pushing Values:
- `stkFunc(0, 5);` pushes the value `5` onto the stack.
- `stkFunc(0, 10);` pushes the value `10` onto the stack.
4. Popping Values:
- The expression `stkFunc(1, 0) + stkFunc(1, 0)` calls the default case twice:
- The first call pops `10`.
- The second call pops `5`.
Final Calculation
- The sum of popped values: `10 + 5 = 15`.
Conclusion
Thus, the value printed by the program is 15, making option C the correct answer.
