How to Get Array Length in Perl - Step by Step Examples
How to Get Array Length in Perl ?
Answer
To get the length of an array in Perl, you can use the scalar
function.
✐ Examples
1 Length of Integer Array
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.
Perl Program
@numbers = (1, 2, 3, 4, 5);
$length = scalar(@numbers);
print "Length of array is: $length\n";
Output
Length of array is: 5
2 Length of String Array
In this example,
- We create a string array named
@names
with some strings. - We use the
scalar
function to get the length of the array and store the returned value in$length
scalar variable. - Finally, we shall print the value in
$length
to standard output.
Perl Program
@names = ("Alice", "Bob", "Charlie");
$length = scalar(@names);
print "Length of array is: $length\n";
Output
Length of array is: 3
