perl foreach loop
A Perl foreach loop is used to iterate over a list or array in Perl. It allows you to perform a specific action on each element of the list. Here is the syntax for a foreach loop in Perl:
foreach my $element (@array) {
# code to be executed for each element
}
In the above syntax, $element
is a scalar variable that represents each element of the array, and @array
is the array that you want to iterate over. The code inside the loop will be executed for each element of the array.
Here's an example of how you can use a foreach loop in Perl:
my @fruits = ("apple", "banana", "orange");
foreach my $fruit (@fruits) {
print "I like $fruit\n";
}
Output:
I like apple
I like banana
I like orange
In the above example, the foreach loop iterates over each element of the @fruits
array and prints a statement for each fruit.
