知名度もあがってきている新星Zig…!

FizzBuzz

Qiitaのコードスペース、Zig対応してくれてますね!

const std = @import("std");

pub fn main() !void {
    var i: u8 = 1;
    // while pattern
    while (i <= 100) : (i += 1) {
        if (i % 15 == 0) {
            std.debug.print("{s}\n", .{"FizzBuzz"});
        } else if (i % 3 == 0) {
            std.debug.print("{s}\n", .{"Fizz"});
        } else if (i % 5 == 0) {
            std.debug.print("{s}\n", .{"Buzz"});
        } else {
            std.debug.print("{}\n", .{i});
        }
    }

    // forでも書けそうだが、forはarrayに対するiterateを想定していそう
    // https://ziglearn.org/chapter-1#for
}
  • 冒頭で次のように宣言すれば、もう少しシュッとprintを呼び出せる。
const print = std.debug.print;
const std = @import("std");
  • forwhileで結構構文が違うんですね?

【参考】コードの作成~コンパイルまで
