Getting Comfortable with Threads in Rust

Objective

Develop a multi-threaded program that demonstrates the use of threads in Rust.

Instructions

1. Spawn Multiple Threads

   • Write a program that spawns a specified number of threads (e.g., 5).
   • Each thread should print its own unique identifier (e.g., thread number).

2. Join Threads

   • Ensure that the main thread waits for all spawned threads to complete before exiting.

3. Experiment

   • Modify the number of threads and observe the output.
   • Change the task performed by each thread to something simple, like counting or performing a calculation.
