[Rust Guide] 1.2. Basic Understanding of Rust and Printing "Hello World"

1.2.0. Side Note I will continue using RustRover for demonstrations in future articles. 1.2.1. Writing Rust Programs File extension: .rs Naming convention: Snake case (lowercase letters, words separated by underscores) Example: hello_world.rs 1.2.2.
