Comments on: Replacing an Else-if Sequence With a Ternary Operator

“One limitation to this technique compared to the else-if sequence is
that there can’t be more that one statement for each conditional.”

This is not quite true as multiple statements per conditional can be separated by a comma. Consider
a > b ? c = d, e = f : c = f, e = d;

Considering wildly varying tab vs space usage and general inability fo people to indent consistently, I can’t think of a single place that this would be better than a series of if and else if statements where the condition and response is on 1 line.

This method is not more readable than

if (…) { displayedChar = … }
if (…) { displayedChar = … }

…

… in any circumstance except to a select group of people. And the if sequence will format correct for anyone without multi-line issues in just about any IDE.

You are awesome, but this seems like an answer in search of a problem.

To better reflect the spec, use a function.

char displayedChar() {
if (x + y >= 30) return ‘.’;
if (x + y >= 25) return ‘/’;
if (x + y >= 20) return ‘o’;
if (x – 3*y > 0) return ‘|’;
if (x – y > 0) return ‘\’;
return ‘_’;
}

Agree for the cuteness of it. But as you mentioned, maybe using it with functions rather than simple cond is better (regarding chenges)
