//
// Quiz time! Let's see if you can fix this whole program.
//
// You'll have to think about this one a bit.
//
// Let the compiler tell you what's wrong.
//
// Start at the top.
//
const std = @import("std");
pub fn main() void {
// What is this nonsense? :-)
const letters = "YZhifg";
// Note: usize is an unsigned integer type used for...sizes.
// The exact size of usize depends on the target CPU
// architecture. We could have used a u8 here, but usize is
// the idiomatic type to use for array indexing.
//
// There IS a problem on this line, but 'usize' isn't it.
const x: usize = 1;
// Note: When you want to declare memory (an array in this
// case) without putting anything in it, you can set it to
// 'undefined'. There is no problem on this line.
var lang: [3]u8 = undefined;
// The following lines attempt to put 'Z', 'i', and 'g' into the
// 'lang' array we just created by indexing the array
// 'letters' with the variable 'x'. As you can see above, x=1
// to begin with.
lang[0] = letters[x];
x = 3;
lang[???] = letters[x];
x = ???;
lang[2] = letters[???];
// We want to "Program in Zig!" of course:
std.debug.print("Program in {s}!\n", .{lang});
