Quadratic Equation Solver

This is simple console script that calculates roots of equation like $ax^2+bx+c=0$, where $a \neq 0$.

There are two mods: interactive and non-interactive (file mode). In interactive mode, user writes coefficients himself. In the non-interactive mode, the coefficients are passed as command line arguments.

Requirements

Node.js v12.16.1 or higher

How to install?

Install git and Node.JS

  sudo apt install nodejs
  sudo apt install git

2.Сlone the repository to your local machine

git clone git@github.com:gonnagetbetter/mtsd-lab1.git

How to use?

You should run such commands in cloned repository

Interactive mode

node main.js

Then you will have oppurtunity to write coefficients and script will calculate roots for you.

File mode

node app.js path/to/file

The script will parse the coefficients from the file and output the roots of the equation.

Note

Your file should have appropriate structure: a b c\n, where a, b and c are the coefficients of the equation and \n is new line symbol. The file shouldn't contain any other symbols or format. It will cause the script to fail.
