How to Iterate over a Two Dimensional Array in Perl - Step by Step Examples
How to Iterate over a Two Dimensional Array in Perl ?
Answer
To iterate over a Two Dimensional Array in Perl, you can use nested loops or the foreach loop.
✐ Examples
1 Iterating over a 2D Array with Nested Loops
In this example,
- We declare and initialize a 2D array named
@matrix
. - We use nested loops to iterate over the rows and columns of the array.
- Inside the inner loop, we access and print each element of the array.
Perl Program
@matrix = ([1, 2], [3, 4], [5, 6]);
foreach my $row (@matrix) {
foreach my $element (@$row) {
print "$element ";
}
print "\n";
}
Output
1 2 3 4 5 6
2 Iterating over a 2D Array with 'foreach' Loop
In this example,
- We declare and initialize a 2D array named
@matrix
. - We use the
foreach
loop to iterate over each row of the array. - Inside the loop, we use another
foreach
loop to iterate over each element of the row and print the element.
Perl Program
@matrix = ([1, 2], [3, 4], [5, 6]);
foreach my $row (@matrix) {
foreach my $element (@$row) {
print "$element ";
}
print "\n";
}
Output
1 2 3 4 5 6
Summary
In this tutorial, we learned How to Iterate over a Two Dimensional Array in Perl language with well detailed examples.
