Note: You cannot use the vector again once you have iterated by taking ownership of the vector.
You can iterate the vector multiple times by taking a reference to the vector whilst iterating.
You can iterate the vector multiple times by taking a reference to the vector whilst iterating.
For example, the following code does not compile.
```rust,ignore
let mut v = vec![1, 2, 3, 4, 5];
let v = vec![1, 2, 3, 4, 5];
for i in v {

Whereas the following works perfectly,
```rust
let mut v = vec![1, 2, 3, 4, 5];
let v = vec![1, 2, 3, 4, 5];
for i in &v {
println!("This is a reference to {}", i);
