Triangle Classification and Area Calculation

Introduction

This C program classifies triangles as Equilateral, Isosceles, Scalene, or Invalid based on user-entered side lengths. It also calculates the area for valid triangles. It's designed for educational purposes, demonstrating geometric principles and mathematical formula applications in programming.

Algorithm

Triangle Type Determination

Logic:

• Validates if side lengths can form a triangle using the triangle inequality theorem.
• Classifies the triangle based on side length comparisons.

Complexity Analysis: Time Complexity: O(1), Space Complexity: O(1).

Triangle Area Calculation

Logic:

• Uses Heron's formula to calculate area.

Complexity Analysis: Time Complexity: O(1), Space Complexity: O(1).

Benefits Over Alternative Approaches

This approach emphasizes input validation, readability, and efficiency by using well-defined functions for each task and constants for triangle types, which enhances maintainability and reduces error likelihood.
