结构元素错误

Question

I have a fast question about the following struct:

typedef struct {
    char folder_name[MAX_FOLDER_NAME];
    Email* emails[MAX_FOLDER_EMAILS];
    int size;
    int empty;
    int protected;
} Folder;

Why Netbeans is not recognizing the "int protected"? The program is saying "unexpected int" and "unexpected ;".

Answer 1

protected是C ++中的关键字，不允许作为变量名。
