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
在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)
