14.10    Solutions

This section provides code solutions for the practice exercises in Section 14.9. The code is largely self-explanatory; however, we have included comments and additional explanations wherever necessary to enhance understanding.

1. Completing multithreaded execution with print statements

   use std::thread;fn main() {    let mut thread_vec = vec![];    for i in 0..10 {        thread_vec.push(thread::spawn(|| {            println!("Hi from the thread");        }));    }    // The code below will make sure that all the threads go to completion    for i in thread_vec {        i.join();    }}  

2. Parallel summation using multiple threads

   use std::thread;fn main() {    let handle_1 = thread::spawn(|| {        let mut sum = 0;        let range = 0..=1_000;        for num in range {            sum += num;        }        sum    });    let ...
