Rust is a statically-typed language, which means that every variable must have a specific type. Rust's type system is designed to be safe and to prevent many common errors that occur in other languages. In this challenge, you will learn about some of the basic primitive data types in Rust, such as integers, floating-point numbers, booleans, and characters.

Understanding how to declare and use these basic data types is fundamental to writing effective Rust code. This challenge will guide you through defining variables with specific types and initializing them.

Your task

  1. Define a variable with type u8 and value 42
  2. Define variable with type f64 and value 3.14
  3. Define variable with type bool and value false
  4. Define variable with type char and value a
  5. In the end, return the tuple (u8, f64, bool, char) with the variables you defined.

Explanation of Data Types

  • Integer (u8): Represents an 8-bit unsigned integer.
  • Floating-point number (f64): Represents a 64-bit floating-point number.
  • Boolean (bool): Represents a boolean value, which can be either true or false.
  • Character (char): Represents a single Unicode scalar value.

Hints

Here are some hints for you if you're stuck:

<details> <summary>Click to show hints</summary>
  • To define a variable of type u8 you can use the syntax let variable_name: u8 = 10;
  • To define a variable of type f64 you can use the syntax let variable_name = 3.14;
  • To define a variable of type bool you can use the syntax let variable_name = false;
  • To define a variable of type char you can use single quotes like let variable_name = 'a';

pub fn data_types() -> (u8, f64, bool, char) {
    // 1. Define variable of type `u8` and value `42`


    // 2. Define variable of type `f64` and value `3.14`


    // 3. Define variable of type `bool` and value `false`


    // 4. Define variable of type `char` and value `a`


    // 5. Return a tuple with the variables in the order they were defined
