Commands continuing on multiple lines

I have the following with && and ||. Because I want to have lines within 80 characters, how can I split this on different lines? Does always need continuation character \ ?

   (( cval != 1 )) && echo "$k" || { echo "" ; printf '%s\n' "${desc[@]}" ; }

how can I split this on different lines?

So just literally put newlines after && and || and after { and instead of or after ;. You can also put comments on separate lines, if you want to.

(( cval != 1 )) &&
   echo "$k" ||
   {
       echo ""
       printf '%s\n' "${desc[@]}"
   }

But really, && || are confusing. Strongly consider an if. And echo "" - just echo.

   if (( cval != 1 )); then
      echo "$k"
   else
      echo
      printf '%s\n' "${desc[@]}"
   fi
