Fundamentals of Data Structures in C++ PDF Download

Fundamentals of Data Structures in C++ is the book PUCIT recommends for the Data Structure and Algorithms course. It is written by Ellis Horowitz, Sartaj Sahni and D. Mehta, and the edition used at PUCIT is the 2nd edition. The book teaches how data is stored, organized and used in programs, with all examples written in C++. If you searched for the Fundamentals of Data Structures in C++ pdf download, this page does not host a PDF file, but it explains how to get the book through legal sources.

Data structures are the backbone of good programs. A program that stores its data well runs faster and is easier to fix. This book starts with the basics and builds up to the structures used in real software, so it suits students who already know C++ basics and want to learn how to write better programs.

About the authors and the edition

The book is written by Ellis Horowitz, Sartaj Sahni and D. Mehta. The PUCIT course outline names the 2nd edition, published by Computer Science Press. The book is written for students, so each new idea is explained in plain steps before the code is shown. The C++ examples are short and focus on the idea, not on tricky language features.

Because the book uses C++, it fits naturally after the programming courses. Students read it after they have learned C in Programming Fundamentals and C++ in Object Oriented Programming. The book assumes the reader can already write simple programs and is ready to learn how to organize data inside them.

What Fundamentals of Data Structures in C++ covers

The book covers the core topics of the subject. It starts with arrays and linked lists, the two simplest ways to store a list of items. Then it moves to stacks and queues, which control the order in which items are added and removed. These four structures appear in almost every program, from a simple student record list to a web browser.

After the basics, the book covers trees and graphs. Trees store data in levels, like folders on a computer, and they make searching fast. Graphs store links between items, like roads between cities or friends in a network. The book also covers sorting and searching, which put data in order and find items quickly, and hashing, which finds an item in almost no time.

Recursion runs through the book as well. Recursion is when a function calls itself to solve a smaller part of the same problem. It is a hard idea at first, but the book shows it with small examples, such as printing a list backwards or walking through a tree. By the end, the reader can pick the right structure for a problem and can explain why it is the right choice.

The book also teaches the reader how to judge whether a structure is fast enough. It explains, in simple terms, how to count the steps a method takes as the data grows. A method that is fine for a hundred items may be far too slow for a million. Learning this way of thinking early saves a lot of pain later, because it stops the reader from picking a structure that works in a test but fails in real use. The book shows this with small tables and examples, so the reader can see the difference instead of just trusting a claim.

Which PUCIT semester uses this book

At PUCIT, this book is used in the 4th semester of all three programs: BS Software Engineering, BS Computer Science and BS Information Technology. The course is called Data Structure and Algorithms. You can see it in the 4th semester lists on the BS Software Engineering books, BS Computer Science books and BS Information Technology books pages.

A note for newer batches: PUCIT and the University of the Punjab have revised their scheme of studies in recent sessions, so the order of some courses may differ for newer batches. You can check the official scheme on the University of the Punjab site.

Who should read this book

This book is for 4th semester PUCIT students taking Data Structure and Algorithms, and for any student who wants a solid grip on data structures in C++. It also helps students who are preparing for coding tests and interviews, because interviewers often ask about linked lists, trees, stacks and sorting.

Before starting this book, you should be comfortable with C++ basics: variables, loops, functions and classes. If you can write a small program on your own, you are ready. Read one chapter at a time, type out the examples, and try the exercises at the end of each chapter. That practice matters more than reading fast.
