Medium Decision Making
Solve in Playground →

Problem Statement

Write a C++ program that checks whether a triangle is valid given its three side lengths (sum of any two sides must be greater than the third).

Input Format

Three space-separated integers A, B, and C.

Output Format

Print 'Valid' or 'Invalid'.

Constraints

Sides > 0

Sample Input

3 4 5

Sample Output

Valid

Explanation

Validates triangle inequality theorem: a + b > c, b + c > a, a + c > b.

Starter Code

#include <iostream>

int main() {
    int a, b, c;
    if (std::cin >> a >> b >> c) {
        // Write your code here
    }
    return 0;
}

Embedded C Programming

Updated: March 15, 2026
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
