Wher is mistake?

Question

using namespace std;

int main ()
{
int a, b, c, d, k, D;
double x, X,y,Y;

cin>>a;
cout<<"b=";
cin>>b;
cout<<"c=";
cin>>c;

cout<<"d=";
cin>>d;
cout<<"k=";
cin>>k;
D=pow(b-d,2)-4*a*(c-k);
x=-b+d-sqrt(D)/2*a;
X=-b+d+sqrt(D)/2*a;
y=d*x+k;
Y=d*X+k;
cout<<"["<<x<<";"<<y<<"]"<<", ["<<X<<","<<Y<<"]"<<endl;
return 0;

}

Answer 1

Did you want to write this code in c language?

Answer 2

Of course it's cpp but just mention that Dima has mentioned c language in his description

Answer 3

That's C++, not C. You need to include <iostream> and <math.h>

Answer 4

Wow, can we please not abuse the tag system like this? 😅

Edit: Thank you for fixing, Nezzie!

Answer 5
