C is a general-purpose programming language that was developed in the early 1970s by Dennis Ritchie at Bell Labs. It is a low-level language, meaning that it provides direct access to the computer's memory and hardware. C is widely used for system and application software, embedded systems, and game development....
C is a high-level, general-purpose programming language that was developed in the early 1970s by Dennis Ritchie at Bell Labs. C is widely used for system and application software, embedded systems, and game development. It is a low-level language, meaning that it provides direct access to the computer's memory and hardware....

Java method overriding is a feature that allows a subclass to provide its own implementation of a method that is already defined in its superclass. When a method is overridden, the subclass implementation of the method is called instead of the superclass implementation....
Java method overloading is a feature that allows a class to have multiple methods with the same name, but with different parameters. Overloading provides a way to create more readable and reusable code by giving the same method name to different methods that perform different tasks....
Java polymorphism is the ability of an object to take on many forms, i.e., an object can have multiple types. In Java, polymorphism is achieved through inheritance, interfaces, and method overloading/overriding....
Java inheritance is a mechanism that allows a class to inherit properties and behaviors from another class. Inheritance is one of the fundamental concepts of object-oriented programming and is used to create hierarchical relationships between classes....
