//
// Behold the 'for' loop! For loops let you execute code for each
// element of an array:
//
// for (items) |item| {
//
// // Do something with item
//
// }
//
const std = @import("std");
pub fn main() void {
const story = [_]u8{ 'h', 'h', 's', 'n', 'h' };
std.debug.print("A Dramatic Story: ", .{});
for (???) |???| {
if (scene == 'h') std.debug.print(":-) ", .{});
if (scene == 's') std.debug.print(":-( ", .{});
if (scene == 'n') std.debug.print(":-| ", .{});
}
std.debug.print("The End.\n", .{});

// Note that 'for' loops also work on things called "slices"
// which we'll see later.
//
// Also note that 'for' loops have recently become more flexible
// and powerful (two years after this exercise was written).
// More about that in a moment.
