how to format multiple conditions assignments in return statement [CLOSED] [Answered]

Greetings, I was wondering, how could I properly format this piece of code.

return
  res > PageCount ?
    -1
    :
    isLastPage ?
      resint > PageItemCount(ItemCount / ItemsPerPage) ?
        -1
        :
        resint
      : resint;

return
  res > PageCount ?
    -1
    :
    isLastPage ?
      resint > PageItemCount(ItemCount / ItemsPerPage) ?
        -1
        :
        resint
      : resint;

You can see I tried to format it somehow, but I don't think it looks good. :D

the way you format that is by changing it to if/if else/else my eyes are crossing just trying to read that

I thought that cond assign is faster than if else in most cases

jcotton42•2y ago

no there's no perf difference not sure where you got that idea from

pan Scott•2y ago

I saw it somewhere, but it was with strings, not ints that's why probably

jcotton42•2y ago

still doesn't make a difference

pan Scott•2y ago

and it was in cpp

jcotton42•2y ago

just change to regular if statements wouldn't be different there either

that's due to a quirk of how C++ handles declarations

std::string blah;
blah = condition ? if-true : if-false;

std::string blah;
blah = condition ? if-true : if-false;

and

std::string blah;
if(condition) {
  blah = if-true;
} else {
  blah = if-false;
}

std::string blah;
if(condition) {
  blah = if-true;
} else {
  blah = if-false;
}

would perform exactly the same also that nested ternary in the video is an unreadable abomination the guy in the video is trying to be really clever but in a bad way don't be "clever" like that, you'll hate yourself down the line
