How to remove the last character of a string in Perl

okwudili onyejiaku

Overview

We can use the chop() method to remove the last character of a string in Perl. This method removes the last character present in a string. It returns the character that is removed from the string, as the return value.

Syntax

chop(str)

Parameters

str: This is the string whose last character we want to remove.

Return value

The value returned is the last character that is removed from the string.

Code example

# create strings
$string1 = "Educative is the best";
$string2 = "Perl language is interesting";
$string3 = "Perl developer";

# remove last strings
$r1  = chop($string1);
$r2 = chop($string2);
$r3 = chop($string3);

# print removed characters
print "$r1\n";
print "$r2\n";
print "$r3\n";

# print strings 
print "$string1\n";
print "$string2\n";
print "$string3\n";

Code explanation

  • Lines 2–4: We create the string values.
  • Lines 7–9: We invoke the chop() method on the strings we created, and then we store the results in the variables $r1, $r2, and $r3.
  • Lines 12–14: We print the characters that were removed, using the chop() method, to the console.
  • Lines 17–19: We print the modified strings to the console.
