Arrays and Hashes

Common Hash Functions: Values

• The values(%Hashname) returns a list of all the current values in a given hash.
• Note that you could do this exact same thing by creating an array from a hash, and returning all the even numbered (odd indexed) elements.
• Example:
  

  $Results{"Bill"} = 1000; 
  $Results{"Bob"} = "forfeit"; 
  $Results{"Betty"} = 6000; 
  @myArray = values(%Results); 
  print "Values in hash are @myArray"\n"; 
  ==> Values in hash are 1000 forfeit 6000 
  

• Warning! The values function in a scalar context gives the number of values in the hash.
• Example (continuing above):
  

  print "Values in hash are " . values(%Results) . "\n";
  ==> Values in hash are 3
