以下代码在编译时给出错误:

int add_employee(struct emp e)
     {
        printf("%i\n", e.emp_no);
        printf("Date of Birth:\n");
        printf("%i / %i / %i\n", e.birth_date.dd, e.birth_date.mm, e.birth_date.yyyy);
        printf("%s %s\n", e.first_name, e.last_name);
        printf("%s\n", e.gender);
        printf("Date of Hirting:\n");
        printf("%i / %i / %i\n", e.hire_date.dd, e.hire_date.mm, e.hire_date.yyyy);
        return 0;
    }

    int main()
    {
        struct employees emp, *ptr;
        ptr = &emp;
        int i=0;
        ptr->emp_no = get_int("Employee No.: ");
        printf("Date of Birth:\n");
        ptr->birth_date.dd = get_int("Date: ");
        ptr->birth_date.mm = get_int("Month: ");
        ptr->birth_date.yyyy = get_int("Year: ");
        ptr->first_name = get_string("First Name: ");
        ptr->last_name = get_string("Last Name: ");
        ptr->gender = get_string("Gender(M/F): ");
       printf("Date of Hiring:\n");
       ptr->hire_date.dd = get_int("Date: ");
       ptr->hire_date.mm = get_int("Month: ");
       ptr->hire_date.yyyy = get_int("Year: ");
      i = add_employee(emp);
       if(i == 0)
       {
           printf("Employee added successfully\n");
       }


以下是我使用clang编译时的错误:

app.c:75:25:警告:“ struct emp”的声明在此功能之外不可见[-Wvisibility]
int add_employee(struct emp e)
                        ^
app.c:75:29:错误:变量的类型'struct emp'不完整
int add_employee(struct emp e)
                            ^
app.c:75:25:注意:“ struct emp”的前向声明
int add_employee(struct emp e)
                        ^
app.c:104:22:错误:参数类型'struct emp'不完整
    i = add_employee(emp);
                     ^ ~~
app.c:75:25:注意:“ struct emp”的前向声明
int add_employee(struct emp e)
                        ^
产生1个警告和2个错误。

最佳答案

main中查看行

struct employees emp, *ptr;


看来类型是struct employees

所以功能应该是

int add_employee(struct employees e)
