Answer 1

rakib.id=1012;
ID is not yet a property of one of the objects.
if you want a teacher, you need to declare one.
staff rakib; // rakikb is a staff member
teacher t1; //t1 is a teacher, this object does have the property pub
char is just one character
since you have referenced std, you can use "string" to declare the name

Answer 2

You need to write you code in the playground first before you can show it

Click on edit post, there should be a + sign at the bottom, click on it and select 'insert code'

Okay, the problem in your code is that your class has no member named id, code...etc. you must first define them inside your class before assigning them
