Create Multiple Nodes

Easy Singly Linked List: Basics
Solve in Playground →

Problem Statement

Write a C program to create two connected nodes in a singly linked list and print their data sequentially.

Input Format

Two space-separated integers for the two nodes.

Output Format

Print the data of both nodes separated by a space.

Constraints

Standard integer limits

Sample Input

10 20

Sample Output

10 20

Explanation

Allocate two nodes, link the first node's next pointer to the second node, and traverse to print both values.

Starter Code

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

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

int main() {
    int val1, val2;
    if (scanf("%d %d", &val1, &val2) == 2) {
        // Write your code here to create two nodes and link them
    }
    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
