Object-Oriented Programming, commonly known as OOP, is a programming paradigm that revolves around the concept of objects. In OOP, software is designed and structured by representing real-world entities, like objects, with attributes (data) and behaviors (methods). OOP has many advantages over Procedural or Procedure Oriented programming (POP).
Mastering Object-Oriented Programming (OOP): Key Principles and Practices
Object-Oriented Programming (OOP) is a widely used paradigm in software development that allows for modular, flexible, and maintainable code. It revolves around the concept of objects, which encapsulate data and behavior.
Algorithm means step-by-step problem solving. That is, to break a problem into several steps and solve each step in turn to solve the entire problem.
A static keyword is very important in object oriented programming. Static methods and properties play a vital role in application design and also in design patterns. So what are static methods and properties? In general, to access any properties or method of a class we first have to initialize an object of that class. Then … Read more
Parameterized Constructor: We know that when we create an object the constructor function gets execution automatically. Consider the following lines of codes, constructor(){ //this is the constructor function a=1; //initializing }void main(){ constructor ob1,ob2; } When this executed the value of ‘a’ for both ob1 and ob2 sets to 1. But when we want different … Read more
Namespace: Namespace defines a scope for the identifiers that are used in the program. To use we will do the following using namespace namespace_name; here, at namespace_name we will give the name of the namespace we want to use. Supposing that we are writing the following, using namespace std; here, std is the … Read more
The this Pointer: When a function of a class is called by an object of that class, each variable gets an pointer which points to that calling object, meaning that this variable was called by that object or this variable is under that object. This pointer is called this pointer. To clarify consider the following … Read more
Function Overloading: Overloading refers to the use of the same thing for different purposes. When the same name for different functions is used that is called function overloading. The functions are then distinguished by their parameters or argument lists. Functions can be overloaded by changing, increasing or decreasing their arguments, float add(float a, float b)int … Read more
Constructor:A constructor is a ‘special’ function whose task is to initialize the objects of its class. It is special because its name is the same as the class name. A constructor is executed whenever object of its class is created. It is called constructor because it constructs the values of data members of the class. … Read more
Properties of Constructor Function: Following are some properties of Constructor Function They will have the same name as of their class. They should be declared in the public section. They are executed automatically when objects are created. They do not have return types, not even void and thus they can’t return values. They can’t be … Read more
