Literal for Double-Quoted Strings in Ruby

If you are creating a program, you may need to put the value of a variable as an output or want to show the string inside a variable.

In Ruby, we use #{} for this purpose. The #{} is used to put the value of a variable in the output text.

In this article, we will see the use of #{} in Ruby, and also we will look at an example relevant to the topic to make the topic easier.

an Example on #{} in Ruby

In our example below, we will illustrate how we can use the #{} in Ruby. Have a look at the below example code.

m = 'This is a string'
puts "Two plus two is #{2 + 2}"
puts "#{m}"

In the example above, we first performed a simple calculation inside the #{} and attached the result with the output.

puts "Two plus two is #{2 + 2}"

After that, we printed the value of variable m through the line below.

puts "#{m}"

Now the whole program will show you the below output.

Two plus two is 4
This is a string
