How to check if Specified Element is present in the Array in Perl - Step by Step Examples

How to check if Specified Element is present in the Array in Perl ?

Answer

To check if a specified element is present in an array in Perl, you can use methods like grep or a loop to iterate through the array and check each element.

✐ Examples

1 Check if Element 30 is present in Integer Array using grep

In this example,

We create an integer array named @numbers with values 10, 20, 30, 40, 50.
We use the grep function to check if element 30 is present in the array.
The grep function returns a list of elements that match the condition, which we check for emptiness to determine if the element is present.

Perl Program

@numbers = (10, 20, 30, 40, 50);
element = 30;
@found_elements = grep { $_ == $element } @numbers;
$is_present = @found_elements ? 'true' : 'false';
print "Element 30 is present: $is_present\n";

Output

Element 30 is present: true

2 Check if Element 'banana' is present in String Array using loop

In this example,

We create a string array named @fruits with values 'apple', 'banana', 'cherry'.
We use a foreach loop to iterate through the array and check each element with the specified element 'banana'.
If the element is found, we set a boolean variable $found to true; otherwise, it remains false.

Perl Program

@fruits = ('apple', 'banana', 'cherry');
element = 'banana';
$found = 0;
foreach $fruit (@fruits) {
    if ($fruit eq $element) {
        $found = 1;
        last;
    }
}
$is_present = $found ? 'true' : 'false';
print "Element 'banana' is present: $is_present\n";

Output

Element 'banana' is present: true
