Data Structure Using C by Balaguruswamy PDF Download

Data structure is a way of organizing and storing data in a computer so that it can be accessed and modified efficiently. Data structure is one of the fundamental topics in computer science and programming. Learning data structure using C language is a good choice for beginners who want to understand the basic concepts and applications of data structures.

One of the popular books on data structure using C is written by E. Balaguruswamy, a former Vice Chancellor of Anna University and a renowned author of several books on programming and software engineering. The book, titled Data Structures Using C, covers various topics such as arrays, stacks, queues, linked lists, trees, graphs, sorting and searching algorithms, and more. The book also explains the run-time complexity of all algorithms and provides many solved examples and unsolved questions to help students practice their skills.

The book is available in both print and digital formats. You can buy the print version from any bookstore or online retailer. You can also download the PDF version of the book from various websites such as Google Books[^1^] [^2^] or Academia.edu[^3^]. However, you should be aware that downloading the PDF version may violate the copyright laws of your country and you should respect the author's rights.

If you are interested in learning data structure using C by Balaguruswamy, you can start by reading the book and following the examples and exercises. You can also find additional resources online such as tutorials, videos, quizzes, etc. to enhance your learning experience. Data structure using C is a useful skill that can help you solve many problems in programming and computer science.

In this section, we will briefly introduce some of the common data structures and their applications in C programming. Data structures can be classified into two types: linear and nonlinear. Linear data structures are those in which the data elements are arranged in a sequential order, such as arrays, stacks, queues, and linked lists. Nonlinear data structures are those in which the data elements are not arranged in a sequential order, such as trees and graphs.

Arrays

An array is a collection of data elements of the same type that are stored in contiguous memory locations. An array can be declared in C using the following syntax:

data_type array_name[size];

where data_type is the type of the data elements, array_name is the name of the array, and size is the number of elements in the array. For example, to declare an array of 10 integers, we can write:

int arr[10];

An array can be initialized with values at the time of declaration or later. To access or modify an element of an array, we use the index operator [], which specifies the position of the element in the array. The index of the first element is 0 and the index of the last element is size-1. For example, to assign 5 to the third element of the array arr, we can write:

arr[2] = 5;

Arrays are useful for storing and manipulating data that have a fixed size and a simple structure. Some of the applications of arrays are:

Implementing mathematical vectors and matrices.

Storing tabular data such as marks, grades, etc.

Sorting and searching algorithms.

Implementing other data structures such as stacks and queues.

Stacks

A stack is a linear data structure that follows the principle of Last In First Out (LIFO), which means that the last element inserted into the stack is the first one to be removed. A stack can be visualized as a pile of plates, where only the top plate can be accessed or removed at any time. A stack can be implemented using an array or a linked list. A stack has two basic operations: push and pop. Push operation adds an element to the top of the stack and pop operation removes and returns the top element from the stack. A stack also has a function called peek, which returns but does not remove the top element from the stack. A stack can be declared in C using a structure that contains an array or a pointer to a linked list and an integer variable that stores the index or size of the stack. For example, to declare a stack using an array of size 10, we can write:

struct stack {

int arr[10];

int top;

};

To initialize a stack, we set its top variable to -1, which indicates that the stack is empty. To push an element into the stack, we increment its top variable by 1 and assign the element to that position in the array. To pop an element from the stack, we return the element at its top position in the array and decrement its top variable by 1. To peek at the top element of the stack, we simply return the element at its top position in the array without changing its top variable. We also need to check if the stack is full or empty before performing any operation on it. A stack is full if its top variable is equal to size-1 and a stack is empty if its top variable is equal to -1.

Stacks are useful for implementing recursive functions, reversing sequences, parsing expressions, backtracking algorithms, etc. Some of the applications of stacks are:

Evaluating postfix expressions.

Converting infix expressions to postfix expressions.

Balancing parentheses and brackets.

Implementing undo and redo features.
