Default Arguments

Default Arguments is simple if you keep it on paper. Meera uses it for Default Arguments on Meera's board in a viva board.

Keep Default Arguments small. Meera should finish Default Arguments on Meera's board in a few lines, not a 40-line dump.

Default Arguments exists so Meera can keep Default Arguments on Meera's board correct in a viva board.

Use Default Arguments when Default Arguments on Meera's board must stay clear. If a simpler PHP step works, use that instead.

Default Arguments trap — only reciting the name of Default Arguments. Meera loses marks for that every viva.

After Default Arguments, Meera should still remember only reciting the name of Default Arguments.

Close Default Arguments with: “If I skip it, Default Arguments on Meera's board goes wrong like this: only reciting the name of Default Arguments.”

Exam tip

Board: Default Arguments on Meera's board. Dry-run Default Arguments. Name the trap: only reciting the name of Default Arguments.

Example

<?php
// Default Arguments
$scores = [80, 90, 70];
$avg = array_sum($scores) / count($scores);
echo "avg=" . number_format($avg, 1) . "\n";
foreach ($scores as $s) {
  if ($s >= 80) echo "high: $s\n";
}

Default Arguments: scores array, print avg, then high marks. Say the output.
