 Hajjagena. In this lesson, we're going to talk about that how to write a function in Rust programming language. Let's go to the website PlayRustLang.org. As you can see every program in Rust programming language has at least one function and that is the main function. Let's write another simple function. Let's say that it will print some text to the console. Let's call our function, for example, print me. And our simple function will not have any argument inside it. And inside our function, let's just print some simple text, for example, hi everyone. Now let's call our function outside of our function. Let's call it, for example, here. Let's zoom out our window and let's run our function. And our function call will call our function. And our function will print hi everyone to the console. That's all in this lesson. See you in some next lesson. Bye-bye.
