How Ternary operator works in C#

Question

i recently try out unity and saw in one of the youtube video clip they code like this:

    Random.Range(0, 2) == 0 ? -1 : 1;

i understand the Random.Range() but what does the the part after mean? thank you in advance

Answer 1

Its the Ternary Operator in C#.

Example:

condition ? expressionResultForTrue : expressionResultForFalse

If Random.Range(0, 2) == 0 evaluates to True we get -1 else 1

Answer 2

Random.Range(0, 2) == 0 ? -1 : 1;

This means, return -1 if Random.Range(0, 2) == 0, else return 1

Answer 3

Accordinaly to Unity documentation, Random.Range receives two parameters, minimum (inclusive) and maximum (exclusive). So it will return 0 or 1. If Random returns 0, this line will return -1, else 1.
