Factorial Program

Factorial Program is a PHP topic. In plain words you use it for a short Factorial Program example in a college portal page. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Factorial Program example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Factorial Program.

From the example next to this theory — Factorial Program: scores array, print avg, then high marks.

Trap — only saying “Factorial Program” with no example. Fix that before you talk about advanced PHP.

Viva — what is Factorial Program? Then show the smallest Factorial Program example you can type. Then name the trap.

Exam tip

What is Factorial Program? Show this: the smallest Factorial Program example you can type. Trap: only saying “Factorial Program” with no example.

Example

<?php
// Factorial 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";
}

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