//
// Now that we've learned about arrays, we can talk about strings.
//
// We've already seen Zig string literals: "Hello world.\n"
//
// Like the C language, Zig stores strings as arrays of bytes
// encoded as UTF-8 characters terminated with a null value.
// For now, just focus on the fact that strings are arrays of
// characters!
//
const std = @import("std");
pub fn main() void {
const ziggy = "stardust";
// Use array square bracket syntax to get the letter 'd' from
// the string "stardust" above.
const d: u8 = ziggy[???];
// Use the array repeat '**' operator to make "ha ha ha".
const laugh = "ha " ???;
// Use the array concatenation '++' operator to make "Major Tom".
// (You'll need to add a space as well!)
const major = "Major";
const tom = "Tom";
const major_tom = major ??? tom;
std.debug.print("d={u} {}{}\n",.{d, laugh, major_tom});
// Going deeper:
// Keen eyes will notice that we've put a 'u' inside the '{}'
// placeholder in the format string above. This tells the
// print() function (which uses std.fmt.format() function) to
// print out a UTF-8 character. Otherwise 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!
