Description: (Compute the perimeter of a triangle) Write a program that reads three edges for a triangle and computes the perimeter if the input is valid. Otherwise, display that the input is invalid. The input is valid if the sum of every pair of two edges is greater than the remaining edge.

(Compute the perimeter of a triangle) Write a program that reads three edges for a triangle and computes the perimeter if the input is valid. Otherwise, display that the input is invalid. The input is valid if the sum of every pair of two edges is greater than the remaining edge.

Key Concepts

Triangle Perimeter

The triangle perimeter is the total distance around the triangle, calculated by summing the lengths of all its three sides. This concept is fundamental in geometry, as it allows for assessing the boundary measure of a triangle, which is crucial in many mathematical and real-world applications.

Triangle Inequality

The triangle inequality is a core condition in geometry which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. This criterion ensures the sides can indeed form a triangle, and any failure to meet this condition indicates the provided measures cannot constitute a valid triangle.

Input Validation

Input validation is a key programming and algorithm concept that involves ensuring the data provided to a program or function meets the necessary criteria before any processing occurs. In the context of calculating a triangle's perimeter, validation checks are performed to verify that the provided edge lengths satisfy the triangle inequality, ensuring the computed perimeter is meaningful.

Conditional Logic

Conditional logic is a programming construct that allows the execution of different sections of code based on whether certain conditions are met. It is used here to decide whether to compute the triangle perimeter if the input is valid or to display an error message if the input fails the triangle inequality test.
