Problem Statement

Write a C program to convert a decimal number to its binary representation using a stack.

Input Format

An integer decimal number.

Output Format

Print the binary representation string.

Constraints

0 <= number <= 1000

Sample Input

10

Sample Output

1010

Explanation

Successive divisions by 2 yield remainder bits which are pushed onto a stack and then popped to form the binary string.

Starter Code

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

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Write your code here to convert decimal to binary using stack
    }
    return 0;
}

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
