PROGRAM TO FIND THE NATURE OF THE ROOTS AS WELL AS VALUE OF THE ROOTS in C plusplus (C++)

Write  a  program to find the nature of the roots as well as value of the roots. However, in case of imaginary roots , find the real part & imaginary part separately.

#include<iostream.h>

#include<conio.h>

#include<math.h>

void main()

{

clrscr();

float a,b,c, r1, r2, d;

cout<<"Enter the coefficients:- ";

cin>>a>>b>>c;

if(a==0)

cout<<"Aborting..";

else

{

d=b*b-4*a*c;

if(d>=0)

{

cout<<"Roots are real ";

if(d>0)

cout<<"and distinct and the values are ";

else

cout<<"and equal and the values are ";

r1=(-b+sqrt(d))/2*a;

r2=(-b-sqrt(d))/2*a;

cout<<r1<<" and "<<r2;

}

else

{

cout<<"Roots are unreal and the values are ";

r1=-b/2*a;

r2=sqrt(-d)/2*a;

cout<<r1<<" +i"<<r2<<" and "<<r2<<" -i"<<r2;

getch();

}

}

}
