Program : To obtain solution of second order quadratic equation

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
float a,b,c;
float desc,root1,root2;
clrscr();
printf("\nEnter the Values of a : ");
scanf("%f",&a);
printf("\nEnter the Values of b : ");
scanf("%f",&b);
printf("\nEnter the Values of c : ");
scanf("%f",&c);
desc = sqrt(b*b-4*a*c);
root1 = (-b + desc)/(2.0*a);
root2 = (-b - desc)/(2.0*a);
printf("\nFirst Root  : %f",root1);
printf("\nSecond Root : %f",root2);
getch();
}

Output :

Enter the Values of a : 1
Enter the Values of a : -5
Enter the Values of a : 6
First Root  : 3.000000
Second Root : 2.000000
