Geo / Cal

Geo / Cal is a simple command-line application written in Rust that calculates the distance between two points in 2D space. This application uses the Euclidean distance formula to provide accurate distance calculations.

Features

• Calculate the distance between two points in 2D space.
• User-friendly command-line interface.
• Handles invalid input gracefully.
• Option to exit the program at any time by entering 'q' or 'quit'.

Installation

You can install Geo / Cal using Cargo, Rust's package manager. Simply run the following command:

cargo install geo-cal

Usage

geo-cal

Entering distance b/n two points. Provide the coordinates.

First coordinates:
Enter x₁: 1
Enter y₁: 1

Second coordinates:
Enter x₂: 4
Enter y₂: 4

We are given: P(1,1) & Q (4,4)

    Formula -> D =  √((x₂ - x₁)²  +  (y₂ - y₁)²)


Step 1. Plug it in -> D = √((4 - 1)² + (4 + 1)²)

Step 2. We now have -> D = √(3² + 3²)

Step 3. Evaluate the squares -> D = √18

The result is D = 4.242640687119285
