尝试使用posix命令在c＆＃x2b;＆＃x2b;

我目前有此代码，我需要使用标准POSIX调用将文本写入文件：

file = open(filename, O_CREAT | O_RDWR | O_APPEND, S_IRUSR | S_IWUSR);
   if (file == -1) {
        perror("File cannot be opened");
        return -1;
    }

但是，每次运行时，我都会获得权限拒绝错误： 无法打开文件：拒绝许可

我尝试在线找到一些东西，并找到此“ cl oper（）函数中的权限”在c 中但是，在尝试这些建议时，我会遇到同样的问题，如果是因为我在使用C+ C for参考时，我正在使用C ++，我正在Mac上，并且正在通过IDE（CLION）运行它，

请提供帮助！

I currently have this code where I need to use standard POSIX calls to write text to a file:

file = open(filename, O_CREAT | O_RDWR | O_APPEND, S_IRUSR | S_IWUSR);
   if (file == -1) {
        perror("File cannot be opened");
        return -1;
    }

However, every time I run it, I get the permission denied error:
File cannot be opened: Permission denied

I tried finding something online and found this "Permission denied" in open() function in C
but when trying those suggestions, I get the same issue and idk if it's because I am using C++ while they were using C. For reference, I am on a Mac and am running this through an IDE (CLion)

please help!
