As mentioned in #2478, this cleans up the code blocks when all that is needed is a trivial debug print statement. Only making changes to Day 1 morning session so that I can get feedback before proceeding with the rest of the course. --------- Co-authored-by: Eric Githinji <egithinji@google.com>

# Loops
|
|
|
|
There are three looping keywords in Rust: `while`, `loop`, and `for`:
|
|
|
|
## `while`
|
|
|
|
The
|
|
[`while` keyword](https://doc.rust-lang.org/reference/expressions/loop-expr.html#predicate-loops)
|
|
works much like in other languages, executing the loop body as long as the
|
|
condition is true.
|
|
|
|
```rust,editable
|
|
fn main() {
|
|
let mut x = 200;
|
|
while x >= 10 {
|
|
x = x / 2;
|
|
}
|
|
dbg!(x);
|
|
}
|
|
```
