In this tutorial, we will learn about arrays in Perl. We will cover the basics of declaring and using arrays, including accessing and modifying elements.
An array is a collection of elements of the same type stored in contiguous memory locations. It allows you to store multiple items under a single name and access them using an index.
The syntax to declare an array in Perl is:
my @array = (elements);
We will learn how to declare, initialize, access, and modify arrays in Perl.
@arr
with 5 elements.my @arr = (1, 2, 3, 4, 5);
foreach my $num (@arr) {
print "$num ";
}
1 2 3 4 5
@arr
with 5 elements.my @arr = (10, 20, 30, 40, 50);
print "The third element is: $arr[2]";
The third element is: 30
@arr
with 5 elements.my @arr = (5, 10, 15, 20, 25);
$arr[1] = 50;
foreach my $num (@arr) {
print "$num ";
}
5 50 15 20 25
