Question

I am working on a project, designed by someone else. I came across the following operation. I have no idea what it is doing. It seems to be returning 1.

Anyone care to elaborate?
Thank you!

   ( 7  > 8?2:1)

Answer 1

You’re looking at the Ternary Operator.

It consists of (condition) ? (expression1) : (expression2). The entire expression will evaluate to (expression1) if (condition) is true, and (expression2) if (condition) is false.

var i = (7 > 8 ? 2 : 1);

translates into

if (7 > 8)
{
  i = 2;
}
else
{
  i = 1;
}
