The ? operator

The if-else statements are so common and widely used in C# that a specialized shorthand notation is available for writing simpler ones, without resorting to the full multiline if-else statements. This shorthand is called the ? operator. The basic form of this statement is as follows:

//If condition is true then do expression 1, else do expression 2
(condition) ? expression_1 : expression_2;

Let's see the ? operator in a practical example as shown here:

//We should hide this object if its Y position is above 100 units
bool ShouldHideObject = (transform.position.y > 100) ? true : false;

//Update object visibility
gameObject.SetActive(!ShouldHideObject);

Tip

The ? operator is useful for shorter statements, but for long and more intricate statements, it can make your code harder to read.
