Circular, Doubly, and Doubly Circular Linked Lists

Let’s explore various linked list structures and their C++ implementations:

Node Class

The foundation of our linked lists is the Node class, representing individual elements:

#include <iostream>
using namespace std;

// Node class represents each element in the linked lists
class Node {
public:
    int data;
    Node* prev;
    Node* next;

    Node(int data) {
        this->data = data;
        this->prev = nullptr;

Understanding Programming Concepts: From Variables to Loops

List the advantages and disadvantages of global variable. Assume the two data files “numl.Txt” and “num2.Txt” containing integers. Merge these two files to the third file named ” file3.Txt”. Here, the integers of ” file3.T-xt” must be written in sorted order. ( 2+ 8 marks)

Sure, let’s start with the advantages and disadvantages of global variables:

Advantages


1.Accessibility: Global variables can be accessed from any part of the program, making them useful for sharing data across different functions

Understanding Flowcharts and Programming Concepts

What do you mean by Flowchart? Draw a flowchart to find the largest among three numbers entered by users. (5 marks)

A flowchart is a graphical representation of a process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. Here’s a flowchart to find the largest among three numbers entered by users:

Start

V Enter first number (num1)

V Enter second number (num2)

V Enter third number (num3)

V if num1 >= num2 and num1 >= num3 then

V Largest = num1

else if num2

Digital Media: Formats, Compression, and Processing

Image Format and Compression

Lossless Compression

Huffman-Encoding: Performing a frequency table.

-RLE (Run Length Encode): Replaces sets of repeated values for a key with a numeric indicator (3 * 2).

-LZW (Lempel-Ziv-Welch): When you find a similar sequence to another, it is replaced by a code of two values, corresponding to how many steps are reversed and how much data is repeated (101 # 32). It is used in GIF or TIFF.

Lossy Compression

.- Method fractal: Divided into blocks, scaling, rotation, we can

Pointers and Arrays in C++

Pointers and Arrays in C++


Pointers


The indirection operator dereferences a pointer, allowing code to work with the value that pointer points to.

int x = 7;
int *iptr = &x;
What will be displayed if you send the expression *iptr to cout? What happens if you send the expression ptr to cout?

The value 7 will be displayed if the expression *iptr is sent to cout. If the expression iptr is sent to cout, the address variable x will be displayed.

Three different uses for the * operator are the multiplication

9: Input Domain Partitioning & Boundary Test Cases

Domain Testing

Generate test cases by assigning specific values to input variables based on analysis of the input domain.

  • Input Space: x1,…,xn represents an input space where each input corresponds to a single data item. Together, they form the input vector. When the vector takes on a specific value, it is called a test point or test case.
  • Input Domain: All points that are allowable input combinations.
  • Sub Domain: Subset
