## Overview

The **`sizeof` method** returns the number of code units in the string multiplied by the size (in bytes) of one code unit.

The code unit value of various types of strings are listed below: 
  * **`ASCIIString`**: 1 byte per character.
  * **`UTF8String`**: 1 byte per character.
* **`UTF16String`**: 2 bytes per character.
* **`UTF32String`**: 4 bytes per character.


## Syntax 

```julia
sizeof(str::AbstractString)
```
## Parameter 
This method takes a string or a character as an argument.

## Return value
This method returns an `integer` value.

## Example

The code below demonstrates how we can use the `sizeof` method:


## Get sizeof the string "Educative"
println(sizeof("Educative"))

## Get sizeof the string  "z"
println(sizeof("z"))

## Get sizeof the character 'z'
println(sizeof('z'))


julia

## Explanation


* **Line 2:** We use the `sizeof` method to get the size of `"Educative"`. We get `9` as the return value. The String values are stored as `UTF-8` which takes only one byte. There are 9 `UTF-8` characters in the string so `9` is returned as the result.

* **Line 5:** We use the `sizeof` method to get the size of `"z"`. We get `1` as the return value.

* **Line 8:** We use the `sizeof` method to get the size of the character `'z'`. We get `4` as the return value because internally the character type (`Char`) is stored as a 32-bit value so that any Unicode codepoint can fit in a `Char`.

How to use the sizeof method of String in Julia

Sizeof returns the number of bytes in a string. For strings, this depends on encoding: ASCII (1 byte), UTF-8 (1 byte), UTF-16 (2 bytes), and UTF-32 (4 bytes).
