Initialization

use std::io;
use std::cmp::Ordering;
use rand::Rng;

• use std::io;: Imports the standard I/O library, allowing input and output operations.
• use std::cmp::Ordering;: Imports the Ordering enumeration, which is used for comparison purposes.
• use rand::Rng;: Imports the Rng trait, which provides methods to generate random numbers.

main Function

fn main() {
    // ...
}

• The main function is the entry point of the Rust program.

Language Selection

let mut language = String::new();

println!("Select your language:");
println!("1 - Português");
println!("2 - English");

io::stdin()
    .read_line(&mut language)
    .expect("Failed to read line");

if language.trim() == "1" {
    portuguese(); 
} else if language.trim() == "2" {
    english();
} else {
    println!("Invalid input. Try again!");
    main();
}

• Prompts the user to select a language (Portuguese or English) and reads their input.
• Based on the user's input, it calls the portuguese function if the input is '1' and the english function if the input is '2'.
• If the user inputs an invalid option, the program displays an error message and restarts the main function.

english Function

fn english() {
    // ...
}

• The english function represents the game logic when the user selects the English language.

Number Guessing Game Logic

fn portuguese() {
    // ...
}

• The portuguese function represents the game logic when the user selects the Portuguese language.

Repeated Game Play

println!("Do you want to play again? (s/n)");
let mut play_again = String::new();
io::stdin()
    .read_line(&mut play_again)
    .expect("Failed to read line");

if play_again.trim().to_lowercase() == "s" {
    main();
} else {
    println!("Thank you for playing!");
}

• Asks the user if they want to play the game again.
• If the user enters 's' or 'S', it restarts the main function for another round.
• If the user enters any other input, the program prints a thank-you message and terminates.
