The Enumerator#each function in Ruby is used to Iterates over the object according to how this Enumerator was constructed and returns the object’s values.
Syntax: A.each { |key, value| print key + ‘ = ‘ + value + “\n” }
Here, A is the initialized object.Parameters: This function accepts constituent of the initialized object as the parameter.
Returns: the constituent elements of the initialized object.
Example 1:
# Initialising a Hash object name_age = { 'name' => 'Geek' , 'age' => '22' }
# Calling the each function C = name_age. each { |key, value| print key + ' = ' + value + "\n" }
# Getting the key and value of hash object puts "#{C}"
|
Output:
name = Geek age = 22 {"name"=>"Geek", "age"=>"22"}
Example 2:
# Initialising a array stooges = [ 'GFG' , 'gfg' , 'Geeks' , 'Geek' ]
# Calling the each function C = stooges. each { |stooge| print stooge + "\n" }
# Getting the values of the array puts "#{C}"
|
Output:
GFG gfg Geeks Geek ["GFG", "gfg", "Geeks", "Geek"]
