Quadratic Equation Solver

This is lab 1 for Software Development Methodologies and Technologies

This tiny CLI program written in Swift lets you solve quadratic equations

Installation

Be sure that you have installed Git to clone the repository and Swift to run script
Clone the repository to you local machine

git clone https://github.com/MrPaschenko/quadratic-equation-solver

Open directory

cd quadratic-equation-solver/Quadratic\ Equation\ Solver

Run script

swift main.swift

Usage

There are two modes supported:

Interactive
Noninteractive

To change mode, comment/uncomment 55/56 lines.

Interactive

Just enter real numbers for a, b, c variables and script will solve the problem!

Welcome to Quadratic Equation Solver!
ax^2 + bx + c = 0
Please, enter real numbers
> a = 2
> b = 1
> c = -3
Equation is: (2.0) x^2 + (1.0) x + (-3.0) = 0
Discriminant is 25.0
There are 2 roots
x1 = 1.0
x2 = -1.5

Noninteractive

Enter path to file to solve the problem.

Welcome to Quadratic Equation Solver!
Please, enter path to file
> Documents/file.txt
Equation is: (1.0) x^2 + (0.0) x + (0.0) = 0
Discriminant is 0.0
There is 1 root
x = -0.0

File’s content should be as follows:
