How do i use the foreach control structure in perl?
-
foreach allows you to process the entire array in perl.
See perlsyn man page: perlsyn(1) - Perl syntax
Takes the animal array and processes each element, printing a line for each animal.
@animals = ("lion", "tiger", "bear", "monkey"); foreach $animal (@animals) { $n += 1; print "Hello, my name is $animal and I'm an animal, in the 100m sprint my number is $n\n"; }
Result is:
Hello, my name is lion and I'm an animal, in the 100m sprint my number is 1
Hello, my name is tiger and I'm an animal, in the 100m sprint my number is 2
Hello, my name is bear and I'm an animal, in the 100m sprint my number is 3
Hello, my name is monkey and I'm an animal, in the 100m sprint my number is 4
