can ternary statements be nested?

[Josh]

 

[Hans Kesting]

yes

coooool,, thanks

Hi there,

Any sample to do nested ternary. Interesting!

Thanks.

Any sample to do nested ternary. Interesting!

int a = 1;

int b = 2;

int c = 3;

int d = 4;

int e = 5;

int f = 5;

int g = 5;

int r;

r = (a<b) ? (c<d) ? e : f : g;



It returns 5

You can nest them, but it's not usually good for readability.

Console.WriteLine((i < 0) ? "negative" : ((i > 0) ? "positive" :
"zero"));

True but Im trying to write a single expression to check for collison
between 3d objects its already a nightmare!!!

I wouldn't create such constructs at all - totally unreadable (even this is
only a sample).

Hi,

It's kind of how you can traverse a matrix using a single for in C
I still remember the first time I delivered a homework with that in the
univ. the teacher gave me a 2 ( suspense in Cuba's grades ) just for that

It's better using two lines of code, or at least separate them in more than
one line, and use parentesis.

Hi,

Then make it the most readable possible something like:

r = (a<b) ?
(c<d) ? e : f
: g;

With one condition per line, instead of all in the same line.

Cheers,

Josh:

I guess you've already heard opinions on readability (I agree, nested
ternarys are hard to read). If you are having to do very complex compares
like this, you might try analysing your logic with a Karnaugh map. You
might find a way to simplify the compares. I've never used one myself, but
I keep this link tucked away, just in case:

I would consider breaking the nested structure into seperate structures only
if that would process quicker. Speed is everything what I'm doing. Some
experiments are needed.
