QuadEquationSolver

A simple program in C that can solve up to quadratic equations.

Installation

Use the following commands to download and compile the program.

git clone https://github.com/nniikon/QuadEquationSolver.git
cd .\QuadEquationSolver
make

Now the only thing left to do is to run KBADRATKA.exe

Usage

Now you can start your program!

.\build\KBADRATKA.exe

While coefficient input is fairly straightforward, equation input might pose more challenges.

• You can utilize the ^ symbol to represent the exponentiation operation

• You can choose whether to include the * multiplication symbol or not.

• You can alse write expressions on both sides of the equal sign

  and they don't necessarily need to be in the conventional order.

Example input / output:

Enter your equation: x^2 - 5x + 12 = 5x^2 + x - 5

Two real roots were found!
x1 = -2.94374
x2 = 1.44374

Please enter coefficient a: 5
Please enter coefficient b: 3.5
Please enter coefficient c: -1.5

Two real roots were found!
x1 = 0.3
x2 = -1

Features

• Various types of inputs can be comprehended:

x^2-x-1 =2*x -x + 12x^2 -5* x | correct input. Take your roots!
-x^2- 5* x^2 = 5x-12*x        | correct input. Take your roots!
x - 5 = 3                     | correct input. Take your roots!
5 = 3x - x^2                  | correct input. Take your roots!
12x=y423-                     | invalid input. Try again:
x^2 - 5x = Hello world!       | invalid input. Try again:
x = 0                         | correct input. But why?
