Sri Manakula vinayagar Engineering College Department of MCA I Year / I Semester MCA Problem 1 The Bashemin parking Garage contains a single lane that holds up to ten cars. There is only a single entrance/exit to the garage at one end of the lane. If a customer arrives to pick up a car that is not nearest the exit, all cars blocking its path are moved out; the customer's cars driven out, and the other cars are restored in the same order that they were in originally. Write a program that processes a group of input lines. Each input line contains an 'A' for arrival or a 'D' for departure, and a license plate number. Cars are assumed to arrive and depart in the order specified by the input. The program should print a message whenever a car arrives or departs. When a car arrives, the message should specify whether or not there is room for the car in the garage. If there is no room, the car leaves without entering the garage. When a car departs, the message should include the number of times that the car was moved out of the garage to allow other cars to depart. Display the result including the details of car number, number of times moved out from the Garage, arrival time, departure time, time taken by the each car while it was in the Garage in a table form. Problem 2 Scratchemup Parking Garage contains a single lane that holds up to ten cars. Cars arrive at the south end of the garage and leave from the north end. If a customer arrives to pick up a car that is not northern most, all cars all cars to the north of the car are moved out, the cars driven out, and the other cars are restored in the same order that they were in originally. Whenever a car leaves, all cars to the south are moved forward so that at all times all the empty spaces are in the south part of the garage. Write a program that reads a group of input lines. Each line contains an 'A' for arrival or a 'D' for departure, and a license plate number. Cars are assumed to arrive and depart in the order specified by the input. The program should print a message whenever a car arrives or departs. When a car arrives, the message should specify Data File Structures using C Lab

whether or not there is a room for the car in the garage. If there is no room, the car leaves without entering the garage. When a car departs, the message should include the number of times that the car was moved out of the garage to allow other cars to depart. Display the result including the details of car number, number of times moved out from the Garage, arrival time, departure time, time taken by the each car while it was in the Garage in a table form. Problem 3 SINGLE LINKED LIST Student admission systems using single linked list. A student database contains maximum of 60 students. Students those who are admitted are added in the list in an alphabetical order. Perform the following operations using single linked list. a. Construct a linear list by accepting the students details like register number, name, age, sex, qualification etc., b. New student will be accepted and admitted anywhere (begin, middle or end) in the list, so that the number of students should not exceed more than 60. After each operation; list should be in the alphabetical order. c. Deleting a student from the list can be performed anywhere (begin, middle or end) in the list and after the operation the list should always in alphabetical order. d. Display the result contains the details of register number, name, age, sex, qualification etc., in a tabular form and also give the details of the total number of students admitted in the class, number of new students added & deleted in the list. Problem 4 Consider a restaurant having one general and another family dining hall with a capacity of 50 and 20 respectively. The numbers of tables with sitting capacities in each section are given below: General Hall 8 seaters 6 seaters 2 Nos. 2 Nos Family Hall 6 seaters 4 seaters 1 No 3 No

4 seaters

3 Nos

2 seaters

1 No

2 seaters 5 Nos Design and Develop an algorithm (or write a program) for the arrival of customers at dinning, bill paying and departure. Consider, there are 5 waiters who have to serve all the incoming customers, 4 washbasins and 1 bill paying counter. Generate the customers arrival time, the number of customers arriving (whether family or individual or group) randomly. Take appropriate time for dining, washing and bill payment. A family with maximum of 6 members and a group with maximum 8 members only can arrive. You are not suppose to accommodate a group of family in different tables and can be given the nearest maximum capacity table (say a group of 5 should only be given a 6 seaters table). In all other situations the customers has to wait. Let the algorithm/program terminate after serving 300 customers. Problem 5 In a double-sided engine passengers train contain 10 compartments. Maximum of 10 passengers are allowed to sit in each compartment and they are allowed to choose the nearest compartment by accessing through either side of the engine. Read the following conditions and write a C program by using the suitable data structure.

(1) Less than 10 passengers in a particular compartment can be filled by the arrival of new passengers but not more than 10 passengers are allowed to sit. Allow the passengers to choose the nearest compartment if there is no enough space to sit in the available one. (2) If the number of passengers are more, than adding a new compartment anywhere between the two engines are allowed to satisfy the passengers convenience. (3) If no passengers are available than remove the particular compartment and make a proper link to continue the journey. (4) Allow the passengers to get down or get into any of these compartments at the stoppages.

(5) List the number of passengers traveled in each compartment at the end of the journey. Problem 6 In a library management system contains the details of title of the book, accession no, author name, cost of the book and date of purchase. Read the following conditions and write a C program by using the suitable data structure. 1. Arrange the books in alphabetical order and you are allowed to access the books either by using accession number or by title of the book. The students are allowed to search and take the book in either of the direction. 2. Purchase of new book will take the accession number followed by the previous accession number and it will be placed only at the last place (No two books should have the same accession number). 3. The books returned by the student can be inserted any where in the order either by using the title of the book or by using accession number. 4. Students are allowed to take the books anywhere in the order but there should not be any gape between the two books. 5. List the number of books issued on that particular date providing the details of student name, accession number, title of the book, author name and cost of the book.
