c – splint调试解析错误

概述这是我第一次使用splint(来自Ubuntu存储库),我立即被WTF击中.错误消息： nightcracker@nightcracker-pc:~/c/brainfuck$splint brainfuck.cSplint 3.1.2 --- 03 May 2009brainfuck.c:17:6: Parse Error. (For help on parse errors, see sp 这是我第一次使用splint(来自Ubuntu存储库),我立即被WTF击中.错误消息：

现在,显然它在第16行第6列看到了错误.让我们检查一下(发布完整代码)：

请注意,此程序编译时没有错误(gcc -Wall -std = c99 brainfuck.c),运行时行为正常.

注意：如果你被名字brainfuck冒犯了,请忍受它.它是一种编程语言,由作者以这种方式命名,我尊重并使用该名称.

解决方法 夹板C99是否有意识？

尝试/ * … * /而不是// …并在任何代码之前移动声明
