我的下一個文本文件，我已經閱讀並的所有行然後打印爲什麼不這段代碼打印文件
ADCA SI IMM 89ii 1 1 2
DIR 99dd 1 1 2
EXT B9hhll 1 2 3
IDX A9xb 1 1 2
IDX1 A9xbff 1 2 3
IDX2 A9xbeeff 1 3 4
[D,IDX] A9xb 1 1 2
[IDX2] A9xbeeff 1 3 4
但不是打印整個文件，它打印：
ADCA SI IMM 89ii 1 1 2
EXT B9hhll 1 2 3
IDX1 A9xbff 1 2 3
[D,IDX] A9xb 1 1 2
也有一些線路失蹤，我不明白爲什麼，但如果我在工作正確行的末尾添加一些製表符，我怎麼能解決這個問題，而不\ t ??下面是代碼：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

你錯過了第二行，所以可能會出現代碼涉及'\ n'的問題。 – moeCake
使用'fgets（）'一次獲取一行並對其進行處理將使得更容易解密流。 – chux
'SearchEndLine（）'應該檢測EOF以及換行符，以防萬一文件的最後一行不以換行符結束。 –
