Use of ternary operator without using assignment or return

Question

Hi I have a problem like

bool isCompleted = true;

if(isCompleted){x= 5}

so i want use above code using ternary operator without using return or assignment like

isCompleted ? int x = 5 : <do nothing>;

So is it possible to use ternary operator without using return or assignment?

Thanks.

Answer 1

You want to set x to 5 if true. Otherwise keep x value?

x = isCompleted ? 5: x:

Answer 2

Try using it like this :

x = isCompleted  ? intValue(if true) : intValue(if false);

Since you have declared x as int, you will have to provide the values in int irrespective of the condition evaluated. Any other type value you use wont work here. Hence the false that you wrote is wrong. You might want to provide an int value there.

Incase if you want to perform some code logic based on bool conditions, you might want to use if...else here as that will help you do more than just assigning some values to variables.

Hope this helps.

Answer 3

You need the assignment prior to the boolean.

x = isCompleted ? 5: 0;

Secondly, you have a type error. The above will set x=5 if isCompleted = true otherwise it will set x=0

isComplete ? 5 :false 

Will fail to compile as you can't assign a boolean to an int.

Answer 4

Read about ternary operator's syntax (MSDN):

The conditional operator (?:) returns one of two values depending on the value of a Boolean expression.

So your code must be rewriten as:

x = isCompleted ? 5 : 0;
