Ternary Operator behaviour in C#

fixed the issue. Will look into that further A ternary operator has a type of its own. That's not always the same as the type of the two operands you pass into the statement. Instead, it's a type that both branches can convert to. In this case, char has an implicit conversion to int. That means the ternary statements type is int. See the example below. The (true ? x : 0).GetType() statement shows how the entire ternary statement has an int type.
code :
public class Program
    {      
      public static void Main(string[] args)
        {
          char x = 'X';
          int i = 0;

          // Prints X fine
          Console.WriteLine(x);

          // Prints System.Int32
          Console.WriteLine((true ? x : 0).GetType());

          // Both print 88 - the int value of 'X'
          Console.WriteLine(true ? x : 0);
          Console.WriteLine(false ? i : x); 
        }
    }

python ternary operator behaviour

Any of those help when I evaluate the following operation
code :
0 if True else 1 + 1 if False else 1
(0) if (True) else ((1 + 1) if (False) else (1))
((0) if (True) else (1)) + ((1) if (False) else (1))

will help you I won't advise you to use such code but for educational purposes it should be
code :
$transport = 'T';
$vehicle = (
        ($transport == 'B') ? 'bus' : 
            (($transport == 'A') ? 'airplane' : 
                (($transport == 'T') ? 'train' : 
                        (($transport == 'C') ? 'car' : 
                                (($transport == 'H') ? 'horse' : 'feet'))))
        );

echo $vehicle;
$transport = 'T';
switch ($transport) {
    case 'A' :
        $vehicle = 'airplane';
        break;
    case 'B' :
        $vehicle = 'bus';
        break;
    case 'C' :
        $vehicle = 'car';
        break;
    case 'H' :
        $vehicle = 'horse';
        break;
    case 'T' :
        $vehicle = 'train';
        break;
    default :
        $vehicle = 'teleportation';
        break;
}

echo $vehicle;
$transport = 'T';
$array = array('A'=>'airplane','B'=>"bus","C"=>"car","H"=>"horse","T"=>"train");
echo isset($array[$transport]) ? $array[$transport] : null;
 SELECT name FROM transpotationTable WHERE someKey = '$transport' 

Unexpected behaviour in ternary operator

Hope that helps Result of ternary (conditional) operator is always of single type - one/both of the options is casted to common type:
code :
var result = condition ? decimalValue : intValue;
public object TurnaryGet
{
    get
    {
        /*decimal*/ var result = condition ? decimalValue : (decimal)intValue;
        return (object)result;
    }
}

Strange Java behaviour. Ternary operator

With these it helps The behaviour is specified in JLS - Conditional Operator:
code :
Float f = true ? testFloat : 0f;
null type - S1
float     - S2

null type - T1 (boxing null type gives null type)
Float     - T2 (float boxed to Float)
