Overloading Rust Macros with macro_rules!

# Introduction

In this lab, you will learn how macros can be overloaded in Rust using the `macro_rules!` syntax, allowing them to accept different combinations of arguments.

> **Note:** If the lab does not specify a file name, you can use any file name you want. For example, you can use `main.rs`, compile and run it with `rustc main.rs && ./main`.
