How to Copy a Set in Perl - Step by Step Examples

How to Copy a Set in Perl ?

Answer

In Perl, you can copy a set (implemented using arrays or other data structures) by creating a new array and assigning the elements of the original set to it.

✐ Examples

1 Copy Integer Set

In this example,

We define an array named @numbers containing some integer elements.
We create a new array named @copiedNumbers and assign the elements of @numbers to it.
Now, @copiedNumbers contains a copy of all elements from @numbers.

Perl Program

my @numbers = (1, 2, 3, 4, 5);
my @copiedNumbers = @numbers;
print "Copied Numbers: @copiedNumbers\n";

Output

Copied Numbers: 1 2 3 4 5

2 Copy String Set

In this example,

We define an array named @fruits containing some string elements.
We create a new array named @copiedFruits and assign the elements of @fruits to it.
Now, @copiedFruits contains a copy of all elements from @fruits.

Perl Program

my @fruits = ("Apple", "Banana", "Cherry", "Date");
my @copiedFruits = @fruits;
print "Copied Fruits: @copiedFruits\n";

Output

Copied Fruits: Apple Banana Cherry Date
