Write a C program to find the roots of a quadratic equation.

Write a C program to find the roots of a quadratic equation.

Program Code:

#include<stdio.h>

#include<math.h>

void main()

{

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

printf("enter the values of equation:");

scanf("%f%f%f",&a,&b,&c);

if(a==0)

printf("\n enter non zero values");

else

{

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

if(d>=0)

{

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

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

printf("\n the roots are=\t%f\t%f",r1,r2);

}

else

printf("\n roots are imaginary");

}

}
