Vector

update vector

let mut v = Vec::new();

v.push(3);
v.push(4);

iterating

let v = vec![23, 45, 6];

for i in &v {
    println!("{}", i);
}

let mut v = vec![12, 23, 34];

for i in mut &v {
    *i += 50;
}

use enum to store different type value

enum SpreadSheetCell {
    Int(i32),
    Float(f64),
    Text(String),
}

let v = vec![
    SpreadSheetCell::Int(23),
    SpreadSheetCell::Text(String::from("blue");),
    SpreadSheetCell::Float(10.3),
];
