And/Or
Let’s say I’m selling movie tickets and we give a discount to people under 18, as well as to people 65 and older. I’d like to write a function gets_discount()
. I can state the requirement in almost-code as age < 18 OR age >= 65
. Unfortunately, that OR
isn’t real Rust code. Instead, it’s time to introduce the or operator, which is two pipes ||
(hold shift and hit the backslash key on most keyboards).
Exercise
Implement the gets_discount
function correctly to make this program pass.
