What are stacks in C programming?

Stacks are a data structure that follows the Last In First Out (LIFO) principle, used for storing data.

How do you implement a stack in C?

You can implement a stack using an array or a linked list. Would you like an example of either?

Yes, please provide an example using an array.

Here's a simple implementation of a stack using an array:

#define MAX 100
int stack[MAX];
int top = -1;

void push(int value) {
    if (top < MAX - 1) {
        stack[++top] = value;
    } else {
        printf("Stack Overflow\n");
    }
}

int pop() {
    if (top >= 0) {
        return stack[top--];
    } else {
        printf("Stack Underflow\n");
        return -1;
    }
}

What are the common operations performed on a stack?

The common operations are push (to add an item), pop (to remove an item), and peek (to view the top item without removing it).
