C requires manual memory management using functions like malloc and free. This hands-on approach helps you understand how memory is allocated and deallocated, which is crucial for writing efficient and bug-free code.

Example:

#include <stdio.h>
#include <stdlib.h>

int main() {
    int *arr;
    int n = 5;

    // Allocate memory for 5 integers
    arr = (int*) malloc(n * sizeof(int));

    if (arr == NULL) {
        printf("Memory allocation failedn");
        return 1;
    }

    // Initialize the array
    for (int i = 0; i < n; i++) {
        arr[i] = i + 1;
    }

    // Print the array
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    printf("n");

    // Free the allocated memory
    free(arr);

    return 0;
}

2.1.2. Pointers

C relies heavily on pointers, which are variables that store memory addresses. Understanding pointers is essential for working with dynamic memory, data structures, and low-level programming.

Example:

#include <stdio.h>

int main() {
    int num = 10;
    int *ptr;

    // Assign the address of num to ptr
    ptr = &num;

    // Print the value of num using ptr
    printf("Value of num: %dn", *ptr);

    // Change the value of num using ptr
    *ptr = 20;

    printf("New value of num: %dn", num);

    return 0;
}

2.1.3. Data Structures

C is excellent for implementing fundamental data structures like linked lists, stacks, and queues. Working with these structures in C helps you understand their underlying mechanics and memory management.

Example:

#include <stdio.h>
#include <stdlib.h>

// Define a structure for a linked list node
struct Node {
    int data;
    struct Node *next;
};

int main() {
    struct Node *head = NULL;
    struct Node *second = NULL;
    struct Node *third = NULL;

    // Allocate memory for the nodes
    head = (struct Node*) malloc(sizeof(struct Node));
    second = (struct Node*) malloc(sizeof(struct Node));
    third = (struct Node*) malloc(sizeof(struct Node));

    // Assign data to the nodes
    head->data = 1;
    second->data = 2;
    third->data = 3;

    // Link the nodes
    head->next = second;
    second->next = third;
    third->next = NULL;

    // Print the linked list
    struct Node *temp = head;
    while (temp != NULL) {
        printf("%d ", temp->data);
        temp = temp->next;
    }
    printf("n");

    // Free the allocated memory
    free(head);
    free(second);
    free(third);

    return 0;
}
