How To Print Variable In Ruby

by

In this blog post, we will discuss how to print variables in Ruby, a popular dynamic, open-source programming language. Ruby is known for its simplicity and ease of use, making it a fan-favorite among both beginner and experienced developers.

Printing Variables with the puts Command

The puts command is the most basic and common way to print a variable in Ruby. It stands for “put string” and can be used to display a variable’s value on the console. The puts method automatically adds a newline character at the end of the output, which means each printed variable will be displayed on a new line.

Here’s an example of how to use the puts command to print a variable: 

    name = "Alice"
    puts "Hello, my name is #{name}."

The code above will output: 

        Hello, my name is Alice.

Printing Variables with the print Command

Another way to print variables in Ruby is by using the print command. Unlike the puts command, the print command does not add a newline character at the end of the output. This means that if you want to print multiple variables using the print command, they will be displayed on the same line.

Here’s an example of how to use the print command to print a variable: 

    name = "Alice"
    print "Hello, my name is #{name}."

The code above will output: 

        Hello, my name is Alice.

Printing Variables with String Interpolation

String interpolation is a powerful feature in Ruby that allows you to directly embed variables inside a string using the #{variable_name} syntax. This can be particularly useful when you want to print a sentence or phrase that includes one or more variables.

Here’s an example of how to use string interpolation to print a variable: 

    name = "Alice"
    age = 30
    puts "Hello, my name is #{name} and I am #{age} years old."

The code above will output: 

        Hello, my name is Alice and I am 30 years old.

Conclusion

In this blog post, we have discussed three different methods to print variables in Ruby: using the puts and print commands, as well as the powerful string interpolation technique. These methods will allow you to easily display variables in your Ruby programs and create dynamic output.
