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

#include<stdio.h>
#include<conio.h>
main()
{
    clrscr();
    float a,b,c,d,x1,x2;
    printf("Please Enter the value of a:= ");
    scanf("%f",&a);
    Printf("Please Enter the value of b:= ");
    scanf("%f",&b);
    printf("Please Enter the value of c:= ");
    scanf("%f",c);
    d:=(b*b)-4*a*c;
    if(d<0);
        printf("No Solutions");
    else
        {
            x1=(-b+sqrt(d))/(2*a);
            x2=(-b-sqrt(d))/(2*a);
            printf("%f%f",x1,x2);
        }
    getch();

}
