Number Triangle Program

Don’t start Number Triangle Program with jargon. Start with Number Triangle Program on Neha's board. That is the whole point.

Number Triangle Program on the board: one Number Triangle Program step Neha can write from memory. Then say what Number Triangle Program on Neha's board looks like after.

Without Number Triangle Program, a first job task gets messy and Number Triangle Program on Neha's board is hard to trust.

Use Number Triangle Program when Number Triangle Program on Neha's board must stay clear. If a simpler PHP step works, use that instead.

Number Triangle Program miss: skipping the failure case for Number Triangle Program. Fix it before you talk about advanced PHP.

After Number Triangle Program, Neha should still remember skipping the failure case for Number Triangle Program.

Viva for Number Triangle Program: what it is → one Number Triangle Program step Neha can write from memory → the mistake (skipping the failure case for Number Triangle Program).

Exam tip

For Number Triangle Program: definition + a first job task + one failure.

Example

<?php
// Number Triangle Program
$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";
}

Number Triangle Program: scores array, print avg, then high marks. Say the output.
