This course provides the best approach to learn Rust, starting from the basics and advancing to complex topics. It is an introduction to Rust for beginners aspiring to become skilled Rust developers.

The word is out: developers love Rust. It's rapidly becoming a top choice for systems and embedded programmers, and the demand for Rust developers is rising. Known for its performance, reliability, and productivity—especially compared to C++—Rust is a powerful language to master. If you're a systems developer, it's a fantastic next step.
In this course, you'll learn Rust by actively engaging in coding. You’ll start with a simple "Hello world" program and cover essential concepts like arrays, strings, vectors, enums, structures, traits, generics, functions, and logic. You'll also dive into advanced topics such as lifetime and memory management.
By the end of this course, you'll have a solid foundation in Rust programming and be well-prepared to take on more advanced concepts, making it ideal for Rust beginners looking to become proficient Rust developers.

Rust Programming Language

# What Is a Function?
A function is a block of code that can be reused. It is used to perform some specific tasks.



- ### `main` Function
  The simplest possible function that we have studied so far is the `main` function that is declared with `fn` keyword.
This is where the program execution starts. 

  However, it is possible to define a user-defined function.


- ### User-defined Functions
  The functions that are **customized** and are written by the programmer to perform the specified tasks.


# Define a Function
A function is declared with the `fn` keyword.
## Syntax
The general syntax is :

This lesson introduces you to an important concept, functions.
