当我编译代码时，我遇到了两个"预期标识符"错误 - 即使它是根据ANSI-C标准编写的。我使用 gcc 编译器编译，带有标志 -Wall -ansi -pedantic。我知道编译器很旧，但我的大学要求我使用它。
复制粘贴错误：
mycomp.c:202:5: error: expected identifier or ‘(’ before ‘return’
return SUCCESS;
^
mycomp.c:203:1: error: expected identifier or ‘(’ before ‘}’ token
}
^
makefile:10: recipe for target 'mycomp.o' failed
我尝试查看我的代码，但找不到任何语法问题。我尝试遵循错误指南行，例如，在"返回"之前添加"（"或在"}"标记之前添加"（"），但这不会改变任何东西，我仍然收到这些错误。
代码又长又乱，但我只在最后或它得到一个错误：最后一个返回和最后一个 } 位数字。

预期结果：编译没有错误，因为这是我唯一得到的 2 个错误。实际结果：出现 2 个错误。
仔细查看并正确缩进代码。
在零件中
} //----------------------- (1)
return SUCCESS; // -----------------------(2)
}
您有一个大括号不匹配，(1)表示main()功能的右大括号，因此标记为(2)的部分; 您的return SUCCESS; }驻留在文件范围内，这是不允许的。
纠正您的压痕并照顾好牙套。
