1. Stack in Array

#include <stdio.h>
#include <stdlib.h> 

#define SIZE 10000
#define INF		99999

int stack[SIZE];
int top = -1;

void push(int data) {
	if (top == SIZE - 1) {
		printf("Stack Overflow !!");
		return;
	}
	stack[++top] = data;
}

int pop() {
	if (top == -1) {
		printf("Stack Underflow !!");
		return -INF;
	}

	return stack[top--];
}

void show() {
	printf("Top Of Stack \n");
	for (int i = top; i >= 0; i--) {
		printf("%d \n", stack[i]);
	}
	printf("Bottom Of Stack \n");
}


int main() {							  
	push(2);
	push(1);
	push(5);
	push(7);
	push(6);
	pop();
	push(8);
	pop();
	push(3);
	show();
	system("pause");
	return 0;
}

2. Stack in Lined List

#include <stdio.h>
#include <stdlib.h>	 
#define INF		99999

typedef struct {
	int data;
	struct Node* next;
} Node;

typedef struct {
	struct Node *top;
} Stack;
					   
void push(Stack *stack, int data) {
	Node* node = (Node*)malloc(sizeof(Node));	

	node->data = data;
	node->next = stack->top;

	stack->top = node;
}

int pop(Stack *stack) {
	if (stack->top == NULL) {
		printf("Stack Underflow !!\n");
		return -INF;
	}

	Node* top = (Node*)malloc(sizeof(Node));
	top = stack->top;
	stack->top = top->next;
	int data = top->data;
	free(top);
	return data;
	
}

void show(Stack *stack) {
	Node* cur = stack->top;

	printf("Top Of Stack \n");
	while (cur != NULL) {
		printf("%d \n", cur->data);
		cur = cur->next;
	}
	printf("Bottom Of Stack \n");
}

int main() {
	Stack stack;
	stack.top = NULL;

	push(&stack, 2);
	push(&stack, 1);
	push(&stack, 5);
	push(&stack, 7);
	push(&stack, 6);
	pop(&stack);
	push(&stack, 8);
	pop(&stack);
	push(&stack, 3);
	show(&stack);
	system("pause");
	return 0;
}
