Write a program to obtain answer by entering a Quadratic function from the ser.(using visual studio)

CODE:

#include<bits/stdc++.h>
using namespace std;
int main()
{
    double a,b,c;
    cout<<"Enter the coefficient for the quadratic term : ";
    cin>>a;
    cout<<"Enter the coefficient for the linear term : ";
    cin>>b;
    cout<<"Enter the coefficient for the constant term : ";
    cin>>c;
    cout<<"Entered Quadratic Function : y = "<<a<<"x^2 + "<<b<<"x + "<<c;
    cout<<"\nAnswer is\n";
    double x1, x2, discriminant, realPart, imaginaryPart;
    discriminant = b*b - 4*a*c;
    
    
    if(a==0 && b==0 && c==0)
        cout<<"00, 00\n";
    else if(a==0)
    cout<<((-1*c)/b)<<"\n";
    
    else if (discriminant > 0) {
        x1 = (-b + sqrt(discriminant)) / (2*a);
        x2 = (-b - sqrt(discriminant)) / (2*a);
        cout<<x1<<" , "<<x2<<"\n";

    }
    else if (discriminant == 0) {
        x1 = -b/(2*a);
        cout << x1<<" , "<< x1 <<"\n";
    }
    else {
        realPart = -b/(2*a);
        imaginaryPart =sqrt(-discriminant)/(2*a);
        cout << realPart << "+" << imaginaryPart << "i" << " , ";
        cout << realPart << "-" << imaginaryPart << "i" <<"\n";
    }
}
