| % Loops |
| |
| <small>There is a new edition of the book and this is an old link.</small> |
| |
| > Rust has three kinds of loops: `loop`, `while`, and `for`. |
| > The `loop` keyword tells Rust to execute a block of code over and over again forever or until you explicitly tell it to stop. |
| > `while` loops evaluate a block of code until a condition ceases to be true. |
| > A `for` loop executes some code for each item in a collection. |
| |
| ```rust,no_run |
| loop { |
| println!("again!"); |
| } |
| |
| let mut number = 3; |
| while number != 0 { |
| println!("{number}!"); |
| number = number - 1; |
| } |
| |
| let a = [10, 20, 30, 40, 50]; |
| for element in a.iter() { |
| println!("the value is: {element}"); |
| } |
| ``` |
