create a function that appends text to a string from an input array in ruby

To create a function that appends text to a string from an input array in Ruby, you can use the following code:

main.rb
def append_text(string, array)
  array.each do |text|
    string << text
  end
  return string
end
99 chars
7 lines

This function takes in two arguments: string, which is the original string you want to append text to, and array, which is an array of strings that you want to append to string.

The function then iterates over each element in array using the each method, and appends each element to string using the << operator.

Finally, the function returns the modified string with the appended text.

You can call this function as follows:

main.rb
text = "Hello, "
array = ["world", " how", " are", " you?"]
result = append_text(text, array)
puts result
106 chars
5 lines

Output:

main.rb
Hello, world how are you?
26 chars
2 lines
