Starter Code

#include <iostream>

// Define isPrime function here

int main() {
    int n;
    if (std::cin >> n) {
        // Call isPrime and print result
    }
    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
