All Programs with Solutions :

 1. Department of Computer Engineering has student's club named 'Pinnacle Club'. Students of second, third and final year of department can be granted membership on request. Similarly one may cancel the membership of club. First node is reserved for president of club and last node is reserved for secretary of club. Write C++ program to maintain club member‘s information using singly linked list. Store student PRN and Name. Write functions to: 
a) Add and delete the members as well as president or even secretary. 
b) Compute total number of members of club 
c) Display members
 d) Two linked lists exists for two divisions. Concatenate two lists. 

2. The ticket booking system of Cinemax theater has to be implemented using C++ program. There are 10 rows and 7 seats in each row. Doubly circular linked list has to be maintained to keep track of free seats at rows. Assume some random booking to start with. Use array to store pointers (Head pointer) to each row. On demand

 a) The list of available seats is to be displayed 

b) The seats are to be booked 

c) The booking can be cancelled. 

3.Write C++ program for storing appointment schedule for day. Appointments are booked randomly using linked list. Set start and end time and min and max duration for visit slot. Write functions for- 

a) Display free slots

 b) Book appointment 

c) Cancel appointment ( check validity, time bounds, availability) d) Sort list based on time e) Sort list based on time using pointer manipulation 

4  Second year Computer Engineering class, set A of students like Vanilla Ice-cream and set B of students like butterscotch ice-cream. Write C++ program to store two sets using linked list. compute and display- 

a) Set of students who like both vanilla and butterscotch 

b) Set of students who like either vanilla or butterscotch or not both 

c) Number of students who like neither vanilla nor butterscotch 

5. Write C++ program for storing binary number using doubly linked lists. Write functions-

 a) To compute 1‘s and 2‘s complement 

 b) Add two binary numbers 

6.Write C++ program to realize Set using Generalized Liked List (GLL)  e.g. A ={ a, b, {c, d,e, {}, {f,g}, h, I, {j,k}, l, m}. Store and print as set notation. 

7. A palindrome is a string of character that‘s the same forward and backward. Typically, punctuation, capitalization, and spaces are ignored. For example, “Poor Dan is in a droop” is a palindrome, as can be seen by examining the characters “poor danisina droop” and observing that they are the same forward and backward. One way to check for a palindrome is to reverse the characters in the string and then compare with them the original-in a palindrome, the sequence will be identical. Write C++ program with functions- 

a) To print original string followed by reversed string using stack b) To check whether given string is palindrome or not . In any language program mostly syntax error occurs due to unbalancing delimiter such as (),{},[]. Write C++ program using stack to check whether given expression is well parenthesized or not. 

8. Implement C++ program for expression conversion as infix to postfix and its evaluation using stack based on given conditions:  1. Operands and operator, both must be single character. 

2. Input Postfix expression must be in a desired format. 

3. Only '+', '-', '*' and '/ ' operators are expected. 

9.A classic problem that can be solved by backtracking is called the Eight Queens problem, which comes from the game of chess. The chess board consists of 64 square arranged in an 8 by 8 grid. The board normally alternates between black and white square, but this is not relevant for the present problem. The queen can move as far as she wants in any direction, as long as she follows a straight line, Vertically, horizontally, or diagonally. Write C++ program with recursive function for generating all possible configurations for 4-queen's problem. 

 10. Queues are frequently used in computer programming, and 

a typical example is the creation of a job queue by an operating system. If the operating system does not use priorities, then the jobs are processed in the order they enter the system. Write C++ program for simulating job queue. Write functions to add job and delete job from queue

11. Write program to implement a priority queue in C++ using an inorder list to store the items in the queue. Create a class that includes the data items (which should be template) and the priority (which should be int). The inorder list should contain these objects, with operator <= overloaded so that the items with highest priority appear at the beginning of the list (which will make it relatively easy to retrieve the highest item.)

12. A double-ended queue (deque) is a linear list in which additions and deletions may be made at either end. Obtain a data representation mapping a deque into a onedimensional array. Write C++ program to simulate deque with functions to add and delete elements from either end of the deque. 

13. Pizza parlor accepting maximum M orders. Orders are served in first come first served basis. Order once placed cannot be cancelled. Write C++ program to simulate the system using circular queue using array.
