Nested Loop with increment on inner loop?


Nested Loop with increment on inner loop?

Any of those help See here to iterate over the array keys. This way you do not need to nest the loops: $i will iterate over 0 1 2, you just need to make sure both arrays have the same number of elements.
code :
#/bin/bash
WEBSITES=(A B C)
DATABASES=(X Y Z)

echo "debug: ${!WEBSITES[@]}"
for i in "${!WEBSITES[@]}"; do
  site=${WEBSITES[$i]}
  db=${DATABASES[$i]}
  echo tar $site
  echo mysqldump $db
done
debug: 0 1 2
tar A
mysqldump X
tar B
mysqldump Y
tar C
mysqldump Z

Why is 'continue' statement ignoring the loop counter increment in 'while' loop, but not in 'for' loop?

Hope this helps Because continue goes back to the start of the loop. With for, the post-operation i++ is an integral part of the loop control and is executed before the loop body restarts.
With the while, the i++ is just another statement in the body of the loop (no different to something like a = b), skipped if you continue before you reach it.

hop of those help? So erm if I understand you correctly, you want to check if every card is only once in your deck? Right? And now you are confused about the output?
So the output is e.g:
code :
Found the card:1:2
Is it good practice to increment a factorial in a for loop's increment statement rather than the body of the for loop?

To fix the issue you can do Do not move loop body into loop header.
The separation of loop components into loop body and loop header greatly improves readability.

hope this fix your issue I have several row in a table in db and every row related with three tables and every table has many rows. when i loop main table rows i also loop three tables rows now if one of tables has a content in row then i want to prevent showing entire sub that loop only which contain a value. , This method uses relationship count comparison.
Controller
code :
public function classWiseResult(Request $request){
    $students = Students::where('class',$request->class)
        ->withCount(['firstTerm as firstTermPromoted' => function($q) {
            $q->where('number', '>', 32);
        }])
        ->withCount('firstTerm as firstTermAllCount')
        ->withCount(['secondTerm as secondTermPromoted' => function($q) {
            $q->where('number', '>', 32);
        }])
        ->withCount('secondTerm as secondTermAllCount')
        ->withCount(['finalTerm as finalTermPromoted' => function($q) {
            $q->where('number', '>', 32);
        }])
        ->withCount('finalTerm as finalTermAllCount')
        ->with('firstTerm')
        ->with('secondTerm')
        ->with('finalTerm')
        ->get();

    return view('admin.showResult.show',compact('students'));
}
@foreach($students as $student)
    @if($student->firstTermPromoted == $student->firstTermAllCount
        && $student->secondTermPromoted == $student->secondTermAllCount
        && $student->finalTermPromoted == $student->finalTermAllCount)

        {{ "Promoted" }}

    @else

        {{ "Not Promoted" }}

    @endif
@endforeach

like below fixes the issue When you iterate over a file object, after completing the iteration the cursor end up at the end of the file . So trying to iterate over it again (in the next iteration of the outer for loop) would not work. The easiest way for your code to work would be to seek to the starting of the file at the start of the outer for loop. Example -
