#ifndef RR_H #define RR_H #include<stdio.h> #define move(c) #define SQRT(c)# define TRANS(c)# define FUNC(c)# #endif 怎麼 #define func(x)___________ ↑ 後面都沒有接條件式然後在它諸多的.cpp中都直接以 " MOVE(1) " MOVE(3) 之類的方式在使用? 指針? 會指到哪裡? 有好幾同一個CPP檔案下的MOVE(1) 後面所描述/*point to________ */ 都不一樣這是@@? 有請高手指點 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.37.17.164
