Example:
int arr[5] = 1, 2, 3, 4, 5;
printf("%d", arr[0]); // prints 1
Example:
typedef struct Stack
int* arr;
int top;
Stack;
Stack* createStack(int size)
Stack* stack = (Stack*) malloc(sizeof(Stack));
stack->arr = (int*) malloc(sizeof(int) * size);
stack->top = -1;
return stack;
void push(Stack* stack, int data)
stack->arr[++stack->top] = data;
int pop(Stack* stack)
return stack->arr[stack->top--];
Example:
typedef struct HashTable
int size;
int* arr;
HashTable;
HashTable* createHashTable(int size)
HashTable* hashTable = (HashTable*) malloc(sizeof(HashTable));
hashTable->size = size;
hashTable->arr = (int*) malloc(sizeof(int) * size);
return hashTable;
void insert(HashTable* hashTable, int key, int value)
int index = key % hashTable->size;
hashTable->arr[index] = value;
Here is a basic C program that uses some of these data structures:
#include <stdio.h>
#include <stdlib.h>
// Node structure for linked list
typedef struct Node
int data;
struct Node* next;
Node;
// Stack structure
typedef struct Stack
int* arr;
int top;
Stack;
// Function to create a new node
Node* createNode(int data)
Node* node = (Node*) malloc(sizeof(Node));
node->data = data;
node->next = NULL;
return node;
// Function to create a stack
Stack* createStack(int size)
Stack* stack = (Stack*) malloc(sizeof(Stack));
stack->arr = (int*) malloc(sizeof(int) * size);
stack->top = -1;
return stack;
// Function to push an element onto the stack
void push(Stack* stack, int data)
stack->arr[++stack->top] = data;
// Function to pop an element from the stack
int pop(Stack* stack)
return stack->arr[stack->top--];
int main()
// Create a linked list
Node* head = createNode(10);
head->next = createNode(20);
head->next->next = createNode(30);
// Print linked list
Node* temp = head;
while (temp != NULL)
printf("%d ", temp->data);
temp = temp->next;
printf("\n");
// Create a stack
Stack* stack = createStack(5);
// Push elements onto the stack
push(stack, 10);
push(stack, 20);
push(stack, 30);
// Pop elements from the stack
printf("%d\n", pop(stack)); // prints 30
printf("%d\n", pop(stack)); // prints 20
printf("%d\n", pop(stack)); // prints 10
return 0;
The provided C program demonstrates the usage of a linked list and a stack. You can expand on this by implementing other data structures and operations. expert data structure with c rb patel pdf cracked
If you want a PDF guide, I can suggest some resources:
You can also search for PDF resources on websites like: Example: int arr[5] = 1, 2, 3, 4,
Keep in mind that some resources might require registration or have limited access.
I'm assuming you're looking for information on a specific book, "Expert Data Structures with C" by RB Patel, and possibly a cracked PDF version. However, I want to guide you on a more constructive and legal approach to accessing educational materials. Example: typedef struct Stack int* arr; int top;
