- // 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.
