// primitive_types3.rs
// Create an array with at least 100 elements in it where the ??? is.
// Scroll down for hints!
fn main() {
let a = ???
if a.len() >= 100 {
println!("Wow, that's a big array!");
} else {

}
// There's a shorthand to initialize Arrays with a certain size that does not
// require you to type in 100 items (but you certainly can if you want!)
// Check out the Primitive Types -> Arrays section of the book:
// https://doc.rust-lang.org/stable/book/second-edition/ch03-02-data-types.html#arrays
// Bonus: what are some other things you could have that would return true
// for `a.len() >= 100`?
