Create simple struct

---

• A simple struct will have one or more fields. Each field has a name and a type.
• We can then create an instance of the struct with actual values.
• We can use the dot-notation to access the values of the fields.
• We cannot change the values unless we declare the struct as mutable using the mut keyword.

examples/struct/point/src/main.rs

struct Point {
    x: i32,
    y: i32
}

fn main() {
    let a = Point {x: 2, y: 3};
    println!("{}", a.x);
    println!("{}", a.y);

    // a.y = 7; // cannot assign to `a.y`, as `a` is not declared as mutable
    // println!("{}", a.y);
}
