% Functions
<small>There is a new edition of the book and this is an old link.</small>
> Function definitions in Rust start with `fn` and have a set of parentheses after the function name.
> The curly brackets tell the compiler where the function body begins and ends.
> We can call any function we’ve defined by entering its name followed by a set of parentheses.
```rust
fn main() {
println!("Hello, world!");
another_function();
}
fn another_function() {
println!("Another function.");
}
```
