我的getline比你的好

显然，有很多缺失，例如： #define R return #define uns unsigned int #define FILE_m ????? #define fopen_m ????? #define GetLine_m ????? ＃定义free_m ????? #define fclose_m ????? 各种包括 如果有人认为_m函数是自定义的还是刚重新定义的ANSI C 函数？ 我宁愿看主要定义为： int main（int argc，char ** argv） 所以，我知道什么是[1]而不必追踪 a是的位置定义。 s是一个指向char的指针，但你没有在C源代码中分配空间。 基于a + = 8; _malloc_m≤（一）;"在下面的神秘代码部分，我怀疑你可能已经为s分配了空间。。但是，在可能被分配的唯一位置之前，你仍然将s设置为零， 而不是NULL。 我的个人偏好是查看参数如此写，return（0）;， notreturn 0; ret 12 我不明白这个神秘的代码部分。你得到了程序集clc， 程序集标签.4，C运算符a + = 8，C-ish stuff_fgetc_m<（k）， 评论带有单个和双正斜杠，还有一堆垃圾 带＃和##。关于唯一可以全部工作的现有语言 一起是FORTH或者广泛的C预处理器滥用... 这个我理解作为x86程序集。它可能实际上是用FASM编译的。 1）C代码：没有。 2）神秘的伪FORTH-FASM-C-mixup：不。 3）x86汇编：是的。 为什么你发布没有人可以使用的代码？既不是a.l.a.或c.l.c.很可能 使用这个......

I''d rather see main defined as:int main(int argc,char **argv) So, that I know what a[1] is without having to track down the location wherea is defined. s is a pointer to char, but you didn''t allocate space in the C source.Based on "a+=8; _malloc_m<(a);" in the cryptic code section below, I suspectthat you may have allocated space for s. However, you still set s to zero,instead of NULL, before the only place where it might be allocated. My personal preference is to see arguments written as such, "return(0);",not "return 0;". ret 12 I don''t understand this cryptic code section. You got assembly "clc",assembly labels ".4", C operators "a+=8", C-ish stuff "_fgetc_m<(k)",comments with both a single and double forward slash, and a bunch of junkwith # and ##. About the only existing language that could that all to worktogether is FORTH or perhaps extensive C pre-processor abuse... This I understand as x86 assembly. It might actually compile with FASM. 1) C code: No.2) cryptic pseudo-FORTH-FASM-C-mixup: No.3) x86 assembly: Yes. Why do you post code nobody can use? Neither a.l.a. or c.l.c. is likely touse this ever...Rod Pemberton 这篇关于我的getline比你的好的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
