A heap, in the context of data structure, is a tree-based data structure that satisfies the heap property, where each element is assigned a key value, or weighting. The lower value key always has a parent node with a higher-value key. This is called a max-heap structure, and among all nodes, the root node has the highest key. Sometimes, a...
Single inheritance enables a derived class to inherit properties and behavior from a single parent class. It allows a derived class to inherit the properties and behavior of a base class, thus enabling code reusability as well as adding new features to the existing code. This makes the code much more elegant and less repetitive. Inheritance is one of the key features of object-oriented programming (OOP). Single inheritance is safer than multiple inheritance if it is approached in the right way. It also enables a derived class to call the parent class implementation for a specific method if this method is overridden in the derived class or the parent class constructor.
The inheritance concept is used in many programming languages, including C++, Java, PHP, C#, and Visual Basic. To implement inheritance, C++ uses the ":" operator, while Java and PHP use the "extend" keyword, and Visual Basic uses the keyword "inherits." Java and C# enable single inheritance only, while other languages like C++ support multiple inheritance.
