Problem Statement

Write a C program to allocate memory dynamically for an integer array using malloc(), assign values, and print them.

Input Format

First line: N. Second line: N space-separated integers.

Output Format

Print the allocated array elements separated by a space.

Constraints

1 <= N <= 1000

Sample Input

3
10 20 30

Sample Output

10 20 30

Explanation

malloc() allocates uninitialized memory block of size N * sizeof(int).

Starter Code

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

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Write your code here
    }
    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
