chomp characters

Example: Copy Code code as follows: #!/bin/perl Print "Please input a string and a number by order!\n"; $the _string=<>; $the _numb=<>; Print "The result is \ n"; Print "$the _string" x "$the _numb"; Results:The

Chomp and chop are all characters used to remove the tail of a string variable, but they have their own differences. The Chomp function works on a variable, and this variable contains a string. If there is a newline character at the end of the

Chomp can remove a line break from the end of a string. This is basically all the functions it can accomplish, as shown in the following example:$ Text = "a line of text/N"; # It can also be input by Chomp ($ text); # Remove the line break (/N ).It
