chop function deletes the character at the right end of the line of text

   

When you type a number 10 and press Enter, the line of input assigned to $originaldist consists of three 
characters: the 1, the 0, and a newline character. 

#!/usr/local/bin/perl 
 
print ("Enter the distance to be converted:\n"); 
$originaldist = <STDIN>; 
chop ($originaldist); 
$miles = $originaldist * 0.6214; 
$kilometers = $originaldist * 1.609; 
print ($originaldist, " kilometers = ", $miles," miles\n"); 
print ($originaldist, " miles = ", $kilometers, " kilometers\n");
