Examples

let mut list_questions: Vec<Question> = Vec::new();
let mut pizza_size = Question::new(String::from("Choose the size of your pizza: "));
pizza_size.add_choice(String::from("Large"));
pizza_size.add_choice(String::from("Medium"));
pizza_size.add_choice(String::from("Small"));
list_questions.push(pizza_size);

let mut pizza_flavor = Question::new(String::from("Choose pizza:"));
let pizza_flavor_choices: Vec<String> = vec![
    String::from("peperoni"),
    String::from("4 cheese"),
    String::from("chicken"),
];
pizza_flavor.add_choices(pizza_flavor_choices);
list_questions.push(pizza_flavor);

let mut prompt = Prompt::new();
prompt.exec(&mut list_questions).unwrap();

let answer_size = list_questions.get(0).unwrap().string_answer().unwrap();
let answer_flavor = list_questions.get(1).unwrap().string_answer().unwrap();
let mut choices_is_correct = Question::new(format!(
    "You choose pizza {} with {}, you confirm?",
    answer_size, answer_flavor
));
choices_is_correct.add_choice(String::from("yes"));
choices_is_correct.add_choice(String::from("no"));
list_questions.clear();
list_questions.push(choices_is_correct);
prompt.exec(&mut list_questions).unwrap();

if let Some(is_correct) = list_questions.get(0).unwrap().string_answer() {
    if is_correct.as_str() == "yes" {
        println!("Great! See ya");
    } else {
        println!("Thats is terrible!! =/ ");
