How to Get Array Length in Perl

How to Get Array Length in Perl ?

To get the length of an array in Perl, you can use the scalar function.

In this example,

We create an integer array named @numbers with some values.
We use the scalar function to get the length of the array and store the returned value in $length scalar variable.
Finally, we shall print the value in $length to standard output.

@numbers = (1, 2, 3, 4, 5);
$length = scalar(@numbers);
print "Length of array is: $length\n";

Length of array is: 5

In this example,

We create a string array named @names with some strings.
We use the scalar function to get the length of the array and store the returned value in $length scalar variable.
Finally, we shall print the value in $length to standard output.

@names = ("Alice", "Bob", "Charlie");
$length = scalar(@names);
print "Length of array is: $length\n";

Length of array is: 3
