PHP Exercises: Check two given integers whether either of them is in the range 100..200 inclusive

PHP Basic Algorithm: Exercise-14 with Solution

Write a PHP program to check two given integers whether either of them is in the range 100..200 inclusive.

Sample Solution:

PHP Code :

<?php
// Define a function named "test" that takes two parameters: $x and $y
function test($x, $y) 
{
    // Check if $x is between 100 and 200 (inclusive) or if $y is between 100 and 200 (inclusive)
    return ($x >= 100 && $x <= 200) || ($y >= 100 && $y <= 200);
}

// Call the test function with arguments 100 and 199, and var_dump the result
var_dump(test(100, 199));

// Call the test function with arguments 250 and 300, and var_dump the result
var_dump(test(250, 300));

// Call the test function with arguments 105 and 190, and var_dump the result
var_dump(test(105, 190));
?>

Explanation:

• Function Definition:
• The test function takes two parameters: $x and $y.
• Condition Check:
• The function checks if:
• $x is between 100 and 200 (inclusive), or
• $y is between 100 and 200 (inclusive).
• If either $x or $y meets this condition, the function returns true; otherwise, it returns false.
• Function Calls and Output:
  • First Call: test(100, 199)
    • $x is 100, which is within the range [100, 200], so it returns true.
  • Second Call: test(250, 300)
    • Neither $x nor $y is within the range [100, 200], so it returns false.
  • Third Call: test(105, 190)
    • Both $x and $y are within the range [100, 200], so it returns true.

Output:

bool(true)
bool(false)
bool(true)

Previous: Write a PHP program to check if one given temperatures is less than 0 and the other is greater than 100.
Next: Write a PHP program to check whether three given integer values are in the range 20..50 inclusive. Return true if 1 or more of them are in the said range otherwise false.
