perl function chop

The chop function in Perl is used to remove the last character from a string. Unlike chomp, chop removes the last character regardless of what it is, so it's typically used when you know exactly what the last character of the string will be.

Here's an example of how to use the chop function:

my $string = "Hello!";
chop $string;
print $string;  # prints "Hello"

In this example, the chop function is used to remove the exclamation mark from the end of the string stored in $string.

It's important to note that chop only removes a single character from the end of the string, so if you want to remove more than one character, you'll need to call chop multiple times. Additionally, if the string is empty, calling chop will have no effect.
