Individual element in an array can be referred with their subscript position in
the array. The first element in an array is always at position "0". An array
structure is always circular.
#!/usr/bin/perl
print "content-type: text/html \n\n";
@array = ("Quarter","Dime","Nickel");
print "@array\n";
print "$array[0]\n"; # Prints the first element in the array
print "$array[1]\n"; # Prints the second element in the array
print "$array[2]\n"; # Prints the third element in the array
print "$array[-1]\n"; # Prints the last element in the array
print "$array[-2]\n"; # Prints second to last element in the array
Output:
-------
