Problem Statement

Write a C++ program defining and immediately invoking a lambda expression (IIFE) to compute and initialize a const variable.

Input Format

Two space-separated integers A and B.

Output Format

Print computed initialization result.

Constraints

-1000 <= A, B <= 1000

Sample Input

10 20

Sample Output

30

Explanation

Immediately Invoked Function Expressions (IIFE) allow complex initialization logic for const variables.

Starter Code

#include <iostream>

int main() {
    int a, b;
    if (std::cin >> a >> b) {
        // Write your IIFE lambda logic here
    }
    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
