Conditional operator not giving correct output

We have an issue that I have been able to recreate with this sample code:

int main()
{
  double d = -2;
  // ...
  cout << "d: " << d << endl;
  cout << "-d: " << -d << endl;
  
  cout << "Conditional Operator (expect value 2): " << (d < 0)? -d : d;
  cout << endl;
  
  return 0;
}

The output is as follows:

d: -2
-d: 2
Conditional Operator (expect value 2): 1

>Solution :

It’s a problem of operator precedence. Use:

cout << "Conditional Operator (expect value 2): " << (d < 0? -d : d);
