Chapter 1

1. Yes, it is The Rust Programming Language by Steve Klabnik and Carol Nichols.
2. In 2015, it was long 64 bits (or 8 bytes). At the end of 2018, it was long 128 bits (or 16 bytes).
3. They are networking, command-line applications, WebAssembly, and embedded software.
4. It checks for non-idiomatic syntax and suggests changes to code for better maintainability.
5. It converts a 2015 edition project to a 2018 edition project.
6. Add this dependency to the Cargo.toml file:

rand = "0.6"

Then, add this code to the main.rs file:

use rand::prelude::*;
fn main() {
    let mut rng = thread_rng();
    let mut numbers = vec![];
    for _ in 0..10 {
        numbers.push(rng.gen_range(100_f32, 400_f32));
    }
    println!("{:?} ", numbers)
}

7. With the dependency used in the previous question, add this code to the main.rs file:

use rand::prelude::*;
fn main() {
    let mut rng = thread_rng();
    let mut numbers = vec![];
    for _ in 0..10 {
        numbers.push(rng.gen_range(100_i32, 401_i32...
