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

# Scope of a variable
The scope of a variable refers to the visibility of a variable, or , which parts of a program can access that variable.

It all depends on where this variable is being declared. If it is declared inside any curly braces `{}`, i.e., a block of code, its scope is restricted within the braces, otherwise the scope is global.





## Types of Variables
There are two types of variables in terms of scope.
### Local Variable
A variable that is within a block of code, `{ }`, that cannot be accessed outside that block is a local variable. After the closing curly brace, `}` , the variable is freed and memory for the variable is deallocated.


### Global Variable
The variables that are declared outside any block of code and can be accessed within any subsequent blocks are known as global variables.

The variables declared using the `const` keyword can be declared in local as well as global scope.
You'll study [constant variables](https://www.educative.io/courses/rust-programming-language/constant-variables) in the next chapter.

This lesson teaches you about the scope of a variable.
