Q1 [Marks: 10]
How can you define a pair of mutually referential structures? Consider the following code
typedef struct {
int afield;
BPTR bpointer;
} *APTR;
typedef struct {
int bfield;
APTR apointer;
} *BPTR;
But the compiler doesn't know about BPTR when it is used in the first structure declaration.
Q2 [marks: 10]
How can you declare a function that can return a pointer to a function of the same type? If you are building a state machine with one function for each state, each of which returns a pointer to the function for the next state.

It is required to make a list of students registered in Data Structures course. To achieve this functionality, develop a C++ program and use linked list to store student ids and names.
Each node in the linked list will contain three items: student id, student name, pointer to next node.
When the program starts, it should display the following menu:
1- Enter student information
2- Search student by ID
3- Search student by Name
4- Delete student information
5- Print all students
6- Quit
Sample Run:
1- Enter student information
2- Search student by ID
3- Search student by Name
4- Delete student information
5- Print all students
6- Quit
Enter your choice: 1 (Suppose user entered 1)
(Now the details of Student will be entered)
Student ID: bc080400001 (Suppose user entered bc080400001)
Student Name: Ahmad (Suppose user entered Ahmad)
(If user enters an ID that is already in the list, a message should be displayed “Already in the list.”
(Main menu will be displayed again)
1- Enter student information
2- Search student by ID
3- Search student by Name
4- Delete student information
5- Print all students
6- Quit
Enter your choice: 2 (Suppose user entered 2)
Student ID: bc080400001 (Suppose user entered bc080400001)
(Now the details of Student will be displayed)
Student ID: bc080400001
Student Name: Ahmad
(If user enters an ID that is not in the list, a message should be displayed “Record not found.”
(Main menu will be displayed again)
1- Enter student information
2- Search student by ID
3- Search student by Name
4- Delete student information
5- Print all students
6- Quit
Enter your choice: 4 (Suppose user entered 4)
(Now it will ask to enter ID to be deleted)
Student ID: bc080400001 (Suppose user entered bc080400001)
(Student record with this ID will be deleted.)
(Main menu will be displayed again)
1- Enter student information
2- Search student by ID
3- Search student by Name
4- Delete student information
5- Print all students
6- Quit
Enter your choice: 5 (Suppose user entered 5)
(Now it will print all students’ information. Suppose there were three students in the list, so it will print: )
Student ID Student Name
------------- ---------------------
bc080400001 Ahmad
bc080200010 Ali
mc070400002 Hassan
(Main menu will be displayed again)
