In Elixir, you can concatenate charlists by using the ++ operator. Charlists are lists of integers, where each integer represents a character in the list. To concatenate two charlists, simply use the ++ operator between the two lists. For example:

list1 = 'hello' list2 = 'world' concatenated_list = list1 ++ list2

Resulting charlist: 'helloworld'

Remember that charlists are different from strings in Elixir, as strings are represented by double-quoted binaries. Charlists are more commonly used when dealing with characters in Elixir, but you can always convert them to strings if needed.

How to concatenate two strings in Elixir?

In Elixir, you can concatenate two strings using the <> operator. Here's an example:

string1 = "Hello" string2 = "World"

concatenated_string = string1 <> " " <> string2 IO.puts(concatenated_string)

This will output: Hello World

What is the size of a charlist in Elixir?

In Elixir, a charlist is represented as a list of characters enclosed in single quotes. The size of a charlist is equal to the number of characters in the list. Each character occupies 1 byte of memory.

How to convert a list of integers to a charlist in Elixir?

In Elixir, you can use the Enum.map/2 function to convert a list of integers to a charlist. A charlist in Elixir is simply a list of characters represented as integers.

Here is an example code snippet that demonstrates how to convert a list of integers to a charlist:

list_of_integers = [65, 66, 67] charlist = Enum.map(list_of_integers, fn x -> :erlang.integer_to_list(x) end) IO.inspect(charlist)

In this example, the Enum.map/2 function is used to iterate over each element in the list_of_integers list and convert each integer value to its corresponding character representation using :erlang.integer_to_list/1 function. The resulting charlist is then stored in the variable charlist.

After running the above code, the IO.inspect(charlist) statement will output the following result:

["A", "B", "C"]
