c - UNIX - 我的主要语法错误

Question

我在以下主语句中遇到语法错误...

int main (int argc, char *argv[]) {

错误显示“意外标记 `(' 附近的语法错误”。

但是，如您所见，此处有适量的括号。有什么问题？

谢谢!

检查您的代码是否有“不可见”字符。根据文件的创建方式，可以获得在普通文本编辑器的正常操作模式下看不到的控制字符和/或 unicode 字符。许多编辑器都有“显示不可见字符”功能(或类似名称的功能)。一些编辑器甚至有一个功能可以找到并删除任何此类字符(例如，OS-X 的 Text Wrangler 中的“Zap Gremlins”。
