Problem Statement

Write a C program to implement a stack using a fixed-size array, initialize its top index to -1, push a given element, and print the stack element.

Input Format

An integer value to push onto the stack.

Output Format

Print the top element of the stack after pushing.

Constraints

Stack capacity >= 100, standard integer limits

Sample Input

Explanation

Define a stack structure with an array and top index. Initialize top = -1, increment top, insert the value, and print stack[top].

Starter Code

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

#define MAX 100

struct Stack {
    int arr[MAX];
    int top;
};

int main() {
    int val;
    if (scanf("%d", &val) == 1) {
        // Write your code here to create stack, push element, and print top
    }
    return 0;
}
