In data mining, there are two major predication problems, namely, classification and regression. The most basic difference between classification and regression is that classification algorithms are used to analyze discrete values, whereas regression algorithms analyze continuous real values. The output variable must be either continuous nature or real value. The output variable in classification has to be a discrete value. In contrast, the output variable in regression must be either continuous in nature or real values. In this article, we will discuss all the important differences between classification and regression. Let's start with some basics of Classification and Regression so ... Read More

Descriptive data mining and predictive data mining are mining techniques that are used to find useful information and patterns in large datasets. Descriptive data mining is a data mining technique that analyzes the past data to provide latest information on past events, while predictive data mining is a data mining technique that is used to analyze past data and provides answers of future queries. Read this this article to learn more about descriptive and predictive data mining techniques and how they are different from each other. What is Descriptive Data Mining? Descriptive data mining is a data mining technique that ... Read More

In object oriented programming, both constructor and destructor are the member functions of a class having the same name as the class. A constructor helps in initialization of an object, i.e., it allocates memory to an object. On the other hand, a destructor deletes the created constructor when it is of no use which means it deallocates the memory of an object. In this article, we will discuss the important differences between constructors and destructors. Let's start with some basic concepts of constructors and destructors. What is a Constructor? A constructor is a member function of a class that initializes ... Read More

In objectoriented programming, there are two important concepts of polymorphism namely, function overloading and function overriding. When two or more functions have the same name but their parameters are different, it is called function overloading. On the other hand, function overriding is one that provides a facility to redefine a function with a name and signature same as the inheriting class. Read this article to learn more about function overloading and overriding in C++ and how they are different from each other. What is Function Overloading? The concept by which we can define different function in a ... Read More

Every programming language has keywords and identifiers. Both keywords and identifiers can be processed by a compiler, however they are quite different from each other. The basic difference between the two is that keywords are the reserve words which are predefined and have a special meaning in the language, whereas an identifier is a unique name assigned to a variable, function, class, etc. Read this article to learn more about keywords and identifiers and how they are different from each other. What is a Keyword? Keywords are reserved words that have a special meaning in a programming language. Therefore, we ... Read More

An Identifier is a name assigned to an entity in a computer program so that it can be identified distinctly in the program during its execution. On the other hand, a variable is a name assigned to a memory location that stores a value. Read this article to learn more about identifiers and variables and how they are different from each other. What is an Identifier? Identifiers are used to name a variable, a function, a class, a structure, a union. In other words, an identifier is created to give a unique name to an entity. It can consist of ... Read More

Array and pointers have a very close relationship in programming, but there are several differences between them. Read this article to find out how Arrays are different from Pointers. But let us first discuss some basics of arrays and pointers. What is an Array? An array is one that stores the values of a homogeneous data type. It refers to a collection that consists of elements of homogenous/same data type. Arrays are considered as a primitive data type. They are declared using the '[ ]' and are stored in contiguous memory locations. Also, arrays use subscripts/ '[ ]' (square brackets) ... Read More

Abstraction is a process of hiding the implementation details of a system from the user, and only the functional details will be available to the user end. On the other hand, Encapsulation is a method of wrapping up the data and code acting on the data into a single unit. Read this article to find out more about abstraction and encapsulation and how they are different from each other. What is Abstraction? Abstraction is defined as a process of hiding the implementation details of a system from the user. Thus, by using abstraction, we provided only the functionality of the ... Read More

In computer programming, Inheritance and Polymorphism are two important concepts. The most basic difference between inheritance and polymorphism is that "inheritance" is a concept of objectoriented programming that allows creating a new class with the help of the features of an existing class, whereas the concept "polymorphism" represents multiple forms of a single function. Read this article to learn more about Inheritance and Polymorphism and how they are different from each other. What is Inheritance? Inheritance is a concept in object-oriented programming (OOP) that refers to the process by which an object can take on the features of one or ... Read More

The "&" and "&&" operators are both logical AND operators in most programming languages, but they can behave differently in certain circumstances. Both "&" and "&&" are operators used for evaluating conditional statements. The most basic difference between the two is that the "&" operator is a logical as well as a bitwise operator, whereas the "&&" operator is only a logical operator. Read this article to find out more about these two operators and how they are different from each other. Let's start with a basic overview of "&" and "&&" operators. What is "&" Operator? The & operator ... Read More
