Write a c program to find the roots of a quadratic equation

#include<stdio.h>
#include<math.h>
int main(){
    int a,b,c;
    double x,y,d;

    printf("Enter a , b , c of quadratic equation: ");
    scanf("%d%d%d",&a,&b,&c);

    //calculating the value of d
    d = sqrt(b * b - 4 * a * c);

    //Checking real solution is possible or not
    if(d<0){
         printf("Real number root is not possible");
         exit(1);
    }
    //finding the root of quadractic equation
    x = (-b + d) / 2 * a;
    y = (-b - d) / 2 * a;

    //printing the root of the quadractic equation
    printf("Solution of quadratic equation are %lf , %lf",x,y);

 
    return 0;
}
