To concatenate a list of characters in Elixir, you can use the <>
operator. This operator can be used to concatenate two lists of characters or a list of characters with a string. Here is an example code snippet to concatenate two lists of characters:
1 2 3 4 |
charlist1 = 'hello' charlist2 = 'world' concatenated_charlists = charlist1 <> charlist2 IO.puts(concatenated_charlists) # Output: helloworld |
In this example, we are concatenating two lists of characters 'hello'
and 'world'
using the <>
operator and storing the result in the concatenated_charlists
variable. The IO.puts
function is then used to print the concatenated charlist.
How to convert a charlist to a string in Elixir?
You can convert a charlist to a string in Elixir by using the List.to_string/1
function. Here's an example:
1 2 3 |
charlist = 'hello' string = List.to_string(charlist) IO.puts string |
This will output:
1
|
"hello"
|
What is the precedence of operators when concatenating charlists in Elixir?
In Elixir, the precedence of operators when concatenating charlists is as follows:
- ++ (concatenation operator) has higher precedence than + (addition operator)
- When concatenating charlists with other operators, it is recommended to use parentheses to clarify the order of operations.
How to reverse a charlist in Elixir?
To reverse a charlist in Elixir, you can simply use the Enum.reverse/1
function. Here is an example:
1 2 3 4 |
charlist = 'hello' # 'hello' is a charlist in Elixir reversed_charlist = Enum.reverse(charlist) IO.inspect(reversed_charlist) # Outputs: 'olleh' |
In this example, we first define a charlist called charlist
with the value 'hello'
. We then use the Enum.reverse/1
function to reverse the charlist and store the result in reversed_charlist
. Finally, we use IO.inspect
to output the reversed charlist.
