我的脚本需要一个输入文件，文件如下所示。从fprintf获取虚假数据

正如你可以看到我的输出看起来不正确的。我从一个字符串中得到一些错误的数据。我无法弄清楚错误。

好吧，关于格式化问题：首先，**不要**对每行代码使用反引号。相反，复制粘贴代码，突出显示所有代码，然后按代码（'{}'）按钮。你可以对其他块做同样的事情，但是我选择了'pre'，因为它没有语法高亮。 – chris 2012-07-23 03:57:39

这些是***变量的可怕***名称。 – dreamlax 2012-07-23 03:58:52

我尽我所能修复了代码。但克里斯是对的，在这里学习格式化工具，并且不要使用反引号 – abelenky 2012-07-23 03:58:55

当代码被编译（在文件bio.c），编译器说：

$ gcc -O3 -g -Wall -Wextra -std=c99 bio.c -o bio 
bio.c: In function ‘main’: 
bio.c:24: warning: too few arguments for format 
bio.c:24: warning: too few arguments for format 
bio.c:17: warning: unused variable ‘two2’ 
bio.c:15: warning: unused variable ‘five’ 
bio.c:9: warning: unused variable ‘i’ 
$

我也懒得来更精确地是哪里的问题制定（第24行是sscanf()为line2 ），但警告表明代码有问题。

读你编译器输出。 GCC给出这个

../../../vmc/_tests/chom.c:23:10: warning: too few arguments for format 
../../../vmc/_tests/chom.c:23:10: warning: too few arguments for format 
../../../vmc/_tests/chom.c:16:22: warning: unused variable ‘two2’ 
../../../vmc/_tests/chom.c:14:32: warning: unused variable ‘five’ 
../../../vmc/_tests/chom.c:8:8: warning: unused variable ‘i’

你想特别担心前两个。
