PHP Exercises: Compute the sum of the two given integers

PHP Basic Algorithm: Exercise-39 with Solution

Write a PHP program to compute the sum of the two given integers. If the sum is in the range 10..20 inclusive return 30.

Sample Solution:

PHP Code :

<?php
// Define a function that checks the sum of two numbers
function test($a, $b)
{
    // Check if the sum of $a and $b is between 10 and 20 (inclusive)
    // If true, return 30; otherwise, return the actual sum
    return $a + $b >= 10 && $a + $b <= 20 ? 30 : $a + $b;
}

// Test the function with different pairs of numbers
echo test(12, 17)."\n";
echo test(2, 17)."\n";
echo test(22, 17)."\n";
echo test(20, 0)."\n";
?>

Sample Output:
