Revising quadratic eqn

#1

Even though the code is executing correctly for all inputs, I am not being able to submit it. pls help!
my code:
#include
#include
using namespace std;

int main() {

float a, b, c, x1, x2, discriminant;
cout << "Enter coefficients a, b and c: "<<"\n";
cin >> a >> b >> c;
if(a==0)
{
    cout<<"this is not a quadratic equation!!"<<"\n";
}
else if(a!=0)
{
    discriminant = b*b - 4*a*c;
        if (discriminant > 0) {
        x1 = (-b - sqrt(discriminant)) / (2*a);
        x2 = (-b + sqrt(discriminant)) / (2*a);
        cout << "Roots are real and different." << endl;
        cout<<x1<<" "<<x2<< endl;
        }

        else if (discriminant == 0) {
        cout << "Roots are real and same." << endl;
        x1 = (-b + sqrt(discriminant)) / (2*a);
        cout <<x1<<" "<<x1<< endl;
        }

        else {
        cout<<"roots are imaginary!"<<"\n";
    }
}
return 0;

}

Hello @gayatri20,

Always share your code using online Coding Blocks IDE.
The way you have shared it may cause syntax errors.
STEPS:

  1. Paste your code on https://ide.codingblocks.com/
  2. Save your code there.
  3. Share the URL generated.

Now, coming back to your question:
Whenever you solve questions, please read the input and output formats carefully.
Example:
cout << “Enter coefficients a, b and c: “<<”\n”;
cout<<“this is not a quadratic equation!!”<<"\n";
cout << “Roots are real and different.” << endl;
cout << “Roots are real and same.” << endl;
cout<<“roots are imaginary!”<<"\n";
All the above mentioned statements are unnecessary and causing wrong output.

I have corrected your code:

NOTE:
If you have downloaded the test cases or unlocked the editorial then you won’t get any marks.
SUGGESTION:
You should only unlock these after scoring full marks for your submission.

Hope, this would help.
Give a like if you are satisfied.
