Quadratic Equation

#1

Sir, see my code
what’s wrong with it .

#2

Hey @sb8031151_af528e7b895c738c You have hard coded the values of a, b and c. Instead you need to take input from user using Scanner.

#3

but still all the test cases are going to be wrong.

#4

Hey @sb8031151_af528e7b895c738c As I can see from your code you still haven’t take any input using Scanner. b and c are still hardcoded.

#5

Sorry sir, I don’t understand the meaning of ‘hardcoded’

#6

Hey @sb8031151_af528e7b895c738c As I can see from your last submitted code you have cured all the errors except on silly mistake.
when roots are real and distinct you have to print exactly :
Real and Distinct
4 7
but you rcode is printing like this :
Roots are real & distinct
4 7
Dont use unnecessary spaces or words bcoz online judge will make your submission for wrong for that . Print exactly like what is given in question.)
Modified code is :

import java.util.*;
public class Main {
    public static void main(String args[]) {

		   Scanner scn= new Scanner(System.in);
        int a=scn.nextInt();
        int b=scn.nextInt();
        int c=scn.nextInt();

        int d=(b*b-4*a*c);
        int r1=(int)(-b-Math.sqrt(d))/2*a;
        int r2=(int)(-b+Math.sqrt(d))/2*a;

       //1
     //System.out.print(d);
        
        if(d>0){
            System.out.println("Real and Distinct");
            System.out.println((int)r1+" "+(int)r2);

        }else if(d==0){
            System.out.println("Real and Equal");
            System.out.println(r1+" "+r2);
        }else{
            System.out.println("Imaginary");
        }

    }
}
