Tech Differences

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...]
