C++ program to find roots of quadratic equation

In this program we will find roots of quadratic equation. For this purpose we will take input of three integers a, b and c. After this we will calculate discriminant. And then we will find two roots, and will store them in variable x1, and x2. And then we will find whether roots are imaginary or real.

    int imaginary_Part=0;
   
   
    cout<<"Enter Value of a: ";
    cin>>a;
   
    cout<<"Enter Value of b: ";
    cin>>b;
   
    cout<<"Enter Value of c: ";
    cin>>c;
   
    d=b*b-4*a*c;
   
    if (d > 0)
    {
        x1 = (-b + sqrt(d)) / (2*a);
        x2 = (-b - sqrt(d)) / (2*a);
        cout << "Roots of quadratic are real and different!" << endl;
        cout << "x1 = " << x1 << endl;
        cout << "x2 = " << x2 << endl;
       }
   
     else if (d == 0)
     {
        cout << "Roots of quadratic equation are real and same." << endl;
        x1 = (-b + sqrt(d)) / (2*a);
        cout << "x1 = x2 =" << x1 << endl;
     }
    
    
     else
     {
        real_Part = -b/(2*a);
        imaginary_Part =sqrt(-d)/(2*a);
        cout << "Roots of quadratic equation are complex and different."  << endl;
        cout << "x1 = " << real_Part << "+" << imaginary_Part << "i" << endl;
        cout << "x2 = " << real_Part << "-" << imaginary_Part << "i" << endl;
    }

}
