*We can use literals to assign values to arrays.
*Demonstrate out of bounds errors by setting n to different values
```
a[n+15] = 11 // index out of bounds error since len is 10
```
*Efficient way to check n is in bounds:
```
assert!(n+20 < a.len()); // panics
```
*In the main function, the print statement asks for the debug implementation with the `?` format parameter: `{a}` gives default output, `{a:?}` gives debug output.
*In the main function, the print statement asks for the debug implementation with the `?` format parameter: `{a}` gives the default output, `{a:?}` gives the debug output.
*Adding `#`, eg `{a:#?}`, invokes a "pretty printing" format, which can be easier to read.
