How do I get the number of hashes inside an array?

  • 772

I have a program that records the data of a person. I created the array personas = [] , empty so that when the user registers, he stores a new hash with his data inside the array personas , thus on gets.chompthe data is obtained one by one; example:

a = gets.chomp
persona = { nombre:a, edad:b, comuna:c, género:d }
personas.push(persona)

The thing is, I want to show the number of registered people in my other options for the client. The question is, how do I convert or display the number of hashes to an integer?

ruby

    Since each person (hash) is an element within the array personas, you only have to display the size of the array, which you can achieve with the Array#size method :

    personas = []
a = gets.chomp
persona = { nombre:a, edad:b, comuna:c, género:d }
personas.push(persona) 

personas.size
#=> 1
