-// Now that we've learned about arrays, we can talk about strings.

-// We've already seen Zig string literals: "Hello world.\n"

-// Zig stores strings as arrays of bytes.

-//     const foo = "Hello";

-// Is the same as:

-    // (Problem 1)
-    // Use array square bracket syntax to get the letter 'd' from
-    // the string "stardust" above.
-    const d: u8 = ziggy[???];

-    // (Problem 2)
-    // Use the array repeat '**' operator to make "ha ha ha".

-    // (Problem 3)

-    //
-    // Keen eyes will notice that we've put a 'u' inside the '{}'
-    // placeholder in the format string above. This tells the
-    // print() function to format the values as a UTF-8 character.
-    // If we didn't do this, we'd see '100', which is the decimal
-    // number corresponding with the 'd' character in UTF-8.
-    //
-    // While we're on this subject, 'c' (ASCII encoded character)
-    // would work in place for 'u' because the first 128 characters
-    // of UTF-8 are the same as ASCII!
