Dave Gauer adf5ddb27d Consistent instructions and examples
I started off with "hints" that required the poor student to piece
together the information from incomplete bits. A complete example is
like a picture that is worth 1000 words and far clearer.

// If statements are also valid expressions:
//
// var foo: u8 = if (a) 2 else 3;
//
// Note: You'll need to declare a variable type when assigning a value
// from a statement like this because the compiler isn't smart enough
// to infer the type for you.
//
// This WON'T work:
//
// var foo = if (a) 2 else 3; // error!

pub fn main() void {
var discount = true;
// Please use an if...else expression to set "price".
// If discount is true, the price should be $17, otherwise $20:
var price = if ???;
std.debug.print("With the discount, the price is ${}.\n", .{price});
