The Flood-fill and boundary-fill algorithm come under the category of area filling algorithm. The crucial differing point in these algorithms is that the flood-fill first checks whether a random pixel is having the region's original colour or not. Conversely, the boundary-fill examines for boundary pixel and it has already been filled or not. Area or region filling is a process of colouring a specific image area or region. These areas can be described based on the pixels or geometric … [Read more...]

While drawing a line on computers they need to perform a set of computation, and it is not that simple as humans can do it in a simple way. So, in computer graphics, there are two algorithms used for drawing a line over the screen that is DDA (Digital Differential Analyser) algorithm and Bresenham algorithm. The chief difference between them is that the DDA algorithm uses floating point values while Bresenham employs integer with round off functions. Furthermore, the implementation of the DDA … [Read more...]

C# and C++ are the programming languages where the C++ is the descendant of the C#. However, C# is derived from C language and it has many features of C and C++, but some features are also dropped in the C#. When it comes to programmer's productivity the C# is miles ahead from C++ and C. The major difference between the C# and C++ lies within its applications where the C# can be used to develop web as well as business applications whereas C++ is useful when the programmer wants to create … [Read more...]

In programming, the solution to a problem is first elucidated in the form of the algorithm which contains sequential steps for the solution. For the programmer convenience, the two forms are evolved to express the algorithm that is Flowchart and Pseudocode. A flowchart is constructed with the help of various symbols and provides more understandability to the algorithm. The algorithm and flowchart are the two sides of the same coin and dependent terms. Creating an algorithm is a very crucial … [Read more...]

The data structure can be defined as the interpretation of logical relationship existing between the solitary elements of data. The linear and non-linear data structure is the subclassification of the data structure which comes under the Non-primitive data structure. The crucial difference between them is that the linear data structure arranges the data into a sequence and follow some sort of order. Whereas, the non-linear data structure does not organize the data in a sequential manner. The … [Read more...]

Definition and Declaration are very confusing terms if you are new to programming. The two concepts are different in some ways as the definition involve memory assignment to the variables while in declaration memory is not allocated. The declaration can be done more than one time, conversely, an entity can be defined exactly once in a program. The definition is automatically a declaration in most of the scenario. Now let's understand the difference between definition and declaration with the … [Read more...]

Insertion sort and selection sort are the techniques used to sort the data. Majorly insertion sort and selection sort can be differentiated by the method they use to sort the data. The insertion sort inserts the values in a presorted file to sort a set of values. On the other hand, the selection sort finds the minimum number from the list and sort it in some order. Sorting is a basic operation in which the elements of an array is arranged in some specific order to enhance its searchability. … [Read more...]

A simple linear queue can be implemented in various three ways, among which one of the types is a circular queue. The difference between linear and circular queue lies in the structural and performance factors. The essential difference between the linear queue and the circular queue is that the linear queue consumes more space than the circular queue, while the circular queue was devised to limit the memory wastage of the linear queue. The queue can be described as non-primitive linear data … [Read more...]

The algorithms are designed using two approaches that are the top-down and bottom-up approach. In the top-down approach, the complex module is divided into submodules. On the other hand, bottom-up approach begins with elementary modules and then combine them further. The prior purpose of an algorithm is to operate the data comprised in the data structure. In other words, an algorithm is used to perform the operations on the data inside the data structures. A complicated algorithm is split … [Read more...]

There are three types of access protection defined in C++ programming language for hiding the data. Data hiding is an essential part of the object-oriented programming. The private and protected keywords offer the level of access protection to hide the data and function within a class. The private members cannot be inherited while the protected member can be inherited but in a limited range. These specifiers indicate the visibility of the members where private is more restrictive than … [Read more...]
