Vecs

• not as performant as arrays.
• only one type.

fn main(){
    let name1 = String::from("Elie");
    let name2 = String::from("Maatouk");

    let mut my_vec = Vec::new();
    my_vec.push(name1);
    my_vec.push(name2);

    println!("{:?}" , my_vec );
}

fn main(){
    let name1 = String::from("Elie");
    let name2 = String::from("Maatouk");
    let mut my_vec: Vec<String> = Vec::new();
    my_vec.push(name1);
    my_vec.push(name2);

    println!("{:?}" , my_vec );

}

fn main(){
    let my_vec = vec![1,2,3];
    println!("{:?}" , my_vec);
}
