To remove the last N characters of a string in Perl, you can use substr function with the length of the string minus N.
In this example,
$str1
with a value of "Hello World"
.$str1 = 'Hello World';
$modified_str = substr($str1, 0, -3);
print 'Modified string is: ' . $modified_str;
Modified string is: Hello Wo
In this example,
$str2
with a value of "apple"
.$str2 = 'apple';
$modified_str = substr($str2, 0, -2);
print 'Modified string is: ' . $modified_str;
Modified string is: app
