Easy Stack: Linked List Implementation
Solve in Playground →

Problem Statement

Write a C program to implement a stack using a linked list, push a single node, and print its value.

Input Format

An integer value to push onto the linked list stack.

Output Format

Print the pushed element.

Constraints

Standard integer limits

Sample Input

42

Sample Output

42

Explanation

Create a node, assign data, point its next to the current top (head), and update top to the new node.

Starter Code

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

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

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

Limits

  • Time Limit: 1s
  • Memory Limit: 256MB

Embedded C Programming

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
