To ternary or not to ternary? [closed]

I’m personally an advocate of the ternary operator: () ? : ; I do realize that it has its place, but I have come across many programmers that are completely against ever using it, and some that use it too often.

What are your feelings on it? What interesting code have you seen using it?

Use it for simple expressions only:

int a = (b > 10) ? c : d;

Don’t chain or nest ternary operators as it hard to read and confusing:

int a = b > 10 ? c < 20 ? 50 : 80 : e == 2 ? 4 : 8;

Moreover, when using ternary operator, consider formatting the code in a way that improve readability:

int a = (b > 10) ? some_value                 
                 : another_value;
