+// Oh dear! It seems we got a little carried away making const u8 values.
+//     * const means constant (cannot be changed)
+//     * u8 means unsigned (cannot be negative), 8-bit integer
+//
+// Hint 1: Use 'var' for values that can change.
+// Hint 2: Use enough bits to hold the value you want:
+//             u8             255
+//             u16         65,535
+//             u32  4,294,967,295
+// Hint 3: Use 'i' (e.g. 'i8', 'i16') for signed integers.
+//
+const std = @import("std");

+    // Perhaps you noticed before that the print function takes two
+    // parameters. Now it will make more sense: the first parameter
+    // is a string. The string may contain placeholders '{}', and the
+    // second parameter is an anonymous struct (data structure)
+    // with values to be printed in place of the placeholders.
