#         
#  Overview
In Ruby, the **`getbyte()` method** is used to return a byte  or  #key# ASCII: American Standard Code for Information Interchange #key# value of a character in a string.  

# 
#  Syntax
```ruby
 int getbyte( int index)
```

# 
## Parameters

This method takes the parameter `index`. It represents the index position of the character whose byte value we want to get.

##
## Return value
It returns an integer value that is the byte representation of a character.

##
## Code


# create a string
str = "Edpresso";

# get byte of some characters and printing them
puts str.getbyte(0) # first character
puts str.getbyte(3) # fourth character
puts str.getbyte(7) # last character

# 
## Explanation
* **Line 2**: We create and initialize a string variable `str`.
* **Lines 5–7**: We call the `getbyte()` method on the string `str` to get the bytes of several characters. We print these using `puts`. Next, we pass the index position value of the characters to `getbyte()`. It returns the bytes of the characters.

When the code above is run, the byte value of the characters is printed to the console.

What is the getbyte() method in Ruby?

Returns byte value (ASCII) of a character in a string using the specified index.
