perl function chomp

The chomp function in Perl is used to remove the newline character (\n) from the end of a string. This function is commonly used to remove the trailing newline that is automatically added when reading input from a file or user input.

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

print "Enter your name: ";
my $name = <STDIN>;  # read input from the user
chomp $name;         # remove trailing newline from $name
print "Hello, $name!\n";

In this example, the chomp function is used to remove the newline character from the end of the input string stored in $name. Without the chomp function, the output would include a newline character at the end of the string, which might not be desired.
