The class is a technique used to bind data and its associated functions together, in contrast, Object is the created instance of a class. The object and class are the terms mainly used in object-oriented programming through which data is organized in the form of objects to reduce the code and application complexity. Objects change their state through the exposed methods and communicate with those methods. On the contrary, classes are passive and do not pass messages but used to create … [Read more...]

The Friend function and friend class are the techniques used to access the private members of a class by using friend keyword. The common difference between friend function and friend class is that when friend function is used the private class members can be accessed but in friend class, only the names of the friend class is accessed not the private members of the class. The friend feature whether used by function or class can produce a negative impact on the object-oriented framework as it … [Read more...]

The major difference between link and association is that link is a physical or theoretical connection between the objects whereas association is a group of links with same structure and semantics. Associations are implemented in programming languages as a reference model in which one object is referenced from the another. While links cannot be referenced as these are not objects by itself, but rely on the objects. The link and association are mostly used in UML designing which can be seen as … [Read more...]

Aggregation and composition are the types of Association. The primary difference between aggregation and composition is that aggregation implicit a relationship where the child can exist independently of the parent. On the other hand, composition insinuates a relationship where the child cannot exist independent of the parent. Object-Oriented programming is a common paradigm which is used in software development. The object is an instance of a class which are created by classes. The objects … [Read more...]

Tree and graph come under the category of non-linear data structure where tree offers a very useful way of representing a relationship between the nodes in a hierarchical structure and graph follows a network model. Tree and graph are differentiated by the fact that a tree structure must be connected and can never have loops while in the graph there are no such restrictions. A non-linear data structure consists of a collection of the elements that are distributed on a plane which means there … [Read more...]

C++ and Java are most commonly used programming languages. Java has a strong influence of C++ as it was developed after C++ and both support OOP (Object Oriented Programming) paradigms. The crucial difference which differentiate both of the programming languages is that C++ is platform dependent while Java is platform independent. Java source code is converted into bytecode when compiled. At runtime, the interpreter executes this bytecode and gives output. Mostly Java is an interpreted … [Read more...]

B-tree and Binary tree are the types of non-linear data structure. Although the terms seem to be similar but are different in all aspects. A binary tree is used when the records or data is stored in the RAM instead of disk as the accessing speed of RAM is much higher than the disk. On the other hand, B-tree is used when the data is stored in the disk it reduces the access time by reducing the height of the tree and increasing the branches in the node. Another difference between the B-tree and … [Read more...]

Sorting is one of the major task in computer programs  in which the elements of an array are arranged in some particular order. Sorting makes searching easier. Bubble sort and Selection sort are the sorting algorithms which can be differentiated through the methods they use for sorting. Bubble sort essentially exchanges the elements whereas selection sort performs the sorting by selecting the element. Another considerable difference between the two is that bubble sort is stable algorithm … [Read more...]

The major difference between BFS and DFS is that BFS proceeds level by level while DFS follows first a path form the starting to the ending node (vertex), then another path from the start to end, and so on until all nodes are visited. Furthermore, BFS uses the queue for storing the nodes whereas DFS uses the stack for traversal of the nodes. BFS and DFS are the traversing methods used in searching a graph. Graph traversal is the process of visiting all the nodes of the graph. A graph is a … [Read more...]

HTML and CSS are the core web scripting languages, the primary use of which is to create web pages and web application. The crucial difference between the two is that HTML is used for the creation of the webpages and CSS is used to control the styling and layout of web pages. In HTML, firstly you write words then add elements or tags to it, which thereafter appear on your page. Through this way, the browser gets to know the heading of the page, beginning and ending of the paragraph, and so … [Read more...]
