I want to create an array of hash like this

array[0] = {'a' => 10, 'b' => 20, 'c' => 30 }
array[1] = {'a' => 10, 'b' => 20, 'c' => 30 }
....

And I want to create the array by adding each element one by one like this

array[1] add {'a' => 10}
array[1] add {'b' => 20}
array[1] add {'c' => 30}

array[2] add {'a' => 10}
array[2] add {'b' => 20}
array[2] add {'c' => 30}

How can I do this?

Answer 1

You could do it like this:

array = []

3.times do |i|
  array[i] = {'a' => 10}
  array[i].merge!({'b' => 20})
  array[i].merge!({'c' => 30})
end

This would populate the array from array[0] to array[2].

Answer 2

Try using merge!:

array[1] = {}
array[1].merge!('a' => 10)
array[1].merge!('b' => 20)
array[1].merge!('c' => 30)
