CS201 Assignment Submission Instructions

You have to submit only .cpp file on the Assignments interface of CS201 at VULMS. Assignment submitted in any other format will not be accepted and will be graded with zero marks.

CS201 Assignment Problem:

Structures are used to overcome the shortcomings of arrays. Basically arrays are used to store more than one data values of a single datatype.

Ex : int a[100] stores integer datatype values

Whereas if you want to make students result database including student_id (int), student_name (char), marks (float) of more than one student, you cannot use array. Here comes the use of structures. Structures are user defined datatypes which allows you to store data of different types.

Example:

struct Student

{

int student_id;

char student_name[50];

float marks;

}s[10];

CS201 Assignment Statement:

Write a menu based system in C++ for “Library Book Record System” that will take input from user for the following menu. You will create a structure and perform the following operations on the structure.

Press 1 To Enter a Book Record.

Press 2 To Display all Records of Books Available in Library.

Press 3 To Search Books by Author Name.

Press 4 To Count Total Books in Library.

Press 5 To Exit from the System.

System will take following inputs from user to enter a book record:

Book ID
Book Title
Author of Book
Cost of Book

CS201 Assignment Solution Instructions:

Use switch statement for the menu based system.

You can use user defined functions for each of the task mentioned above to manage your code.

To Enter a Book Record Add_Book();

To Display all Records of Books Available in Library Display_Books();

To Search Books by Author Name Book_Author();

Count Total Books in Library Count_Books();

Please Note:
You also need to Restrict your system that it do not allow to add more than 5 books and on try of adding books more than limit show message i.e. “No more space in System for another book”.

Use strcmp function to search books by author name in Book_Author(); function.
