Here is a hash

```
personal_details = {
  name: name,
  dob: dob,
  age: age,
  height: height
}

```

Here is an array

```
puts "What are the name of some of your relatives? (eg. Bob, James, Harry etc)"
relatives = gets().chomp.split(",")

```

Lets say the input for relatives was "Bob, James, Harry". 

I want the hash to look like this:

```
personal_details = {
  name: name,
  dob: dob,
  age: age,
  height: height
  relatives: [
         {name: Bob},
         {name: James},
         {name: Harry}
  ]
}

```

The array in the hash is updated based on user input.
