    float a=0,b=0,c=0,d=0;
    float a1=2,a2=-2,a3=-2,b1=3,b2=4,b3=-1,c1=4,c2=8,c3=4;
    a =(b2-a2)*(c3-a3)-(c2-a2)*(b3-a3);
    b =(b3-a3)*(c1-a1)-(c3-a3)*(b1-a1);
    c =(b1-a1)*(c2-a2)-(c1-a1)*(b2-a2); 
    d =-(a*a1+b*a2+c*a3); 
    printf("Equation of the plane(given three points) %f x+ %f y+ %f z+ %f = 0",a,b,c,d);
    return 0;
