@Hughpig 艹，大意了

by __er @ 2022-09-07 19:58:24

啊这样不行？

printf("%c%c%c%c%c", getchar(), getchar(), getchar(), getchar(), getchar());

@Arlex 按位拆完直接输出，不用计算和

by fortyyearslater @ 2022-09-07 20:07:14

@__er 那这不还是按序输出吗(没试过)

by __er @ 2022-09-07 20:08:58

@fortyyearslater printf 从后往前执行函数，再从前往后输出，特性

@__er 哦哦
