Boring C code ever! - solve quadratic equations

( Giải phương trình bậc hai dùng ngôn ngữ C )
Doing all of the calculation in only 1 code line for solving quadratic equation
How boring it is, isn't it :D

#include

void main()
{
    double a,b,c;
    printf("=======================================\n=============== GPTB 2 ================\n=======================================\nNhap du lieu a,b,c cua phuong ax^2 + bx + c = 0\n");
    printf("Nhap a = "); scanf("Nhap a = %lf",&a);
    printf("\n");
    printf("Nhap b = "); scanf("%lf",&b);
    printf("\n");
    printf("Nhap c = "); scanf("%lf",&c);
    printf("\n");

    (a == 0)?((c==0)?((b == 0)?printf("PT vo so nghiem\n"):printf("PT vo nghiem")):((b == 0)?printf("PT vo nghiem\n"): printf("PT co 1 nghiem: %lf",-c/b))):((c != 0) ?
