Arrays and Hashes

Chomp

• The chomp function takes an array and removes the trailing \n character from each element in the array.
• Example:
  

  $First[0] = <STDIN>; 
  $First[1] = <STDIN>; 
  $First[2] = <STDIN>; 
  chomp(@First); 
  

• Note that this is different then sort or reverse , where a modified copy of the array was returned. In this case, the existing array was actually modified.
• This is grossly inconsistent from a theoretical point of view, but from a practical point of view, really does not amount to a hill of beans, and probably is helpfull.
