dereferencing pointer to incomplete type
出现了这个提示，目前还未解决
1
写代码的时候左边会显示写的行数？
1.因为cpu智能识别0.1
2.0.1
3.编译
4.可以
5.翻译器
为什么我是110行我自己输入和复制粘贴都是110
看看答案
我就看看那个摩斯密码
HAHAHA
{:9_221:}
{:5_109:}
1111
11111111111111
0.因为计算机只懂得0和1
1.机器语言
2.编译
3.\
4.不能
5.通过解码器
6.\

显示出错是什么情况
C:\Users\zzbo9\AppData\Local\Temp\cccFww9i.o 试一试.c:(.text+0x147): undefined reference to `countLines'
G:\FishC\S1e2\collect2.exe ld returned 1 exit status
对照了一下，发现了好多错，但还是完成了！

0. 只懂二進制的0和1
1. 機器語言
2. 編譯
3. 編譯型語言做出來的機器瑪可以直接被CPU執行 解釋型語言寫出來的字節碼需要被解釋氣解釋後才能被CPU執行
4. 否
5.
6.
7.翻譯出來了看不懂...
一直顯示總共寫了7行代碼

0： 计算机智能识别0和1
1：机械语言
2：编译
3：不能
加油
有点难受 错了不少
来对对答案
