Sometimes it is required to initialize some part of an object before it can be utilized. For example, we are operating on the stack, before we perform any action, the top of the stack must always be set to zero. This feature of automatic initialization is performed through 'Constructor'. Likely, if an object needs to execute some code before it is destroyed. For example, if an object needs to close a file that it had opened, before its destruction. It can be performed with the help of … [Read more...]

Procedure-oriented Programming(POP) and Object-oriented programming(OOP) both are the programming approaches, which uses high-level language for programming.A Program can be written in both the languages, but if the task is highly complex, OOP operates well as compared to POP. In POP, the 'data security' is at risk as data freely moves in the program, as well as, 'code reusability' is not achieved which makes the programming lengthy, and hard to understand. Large programs lead to more bugs, and … [Read more...]

Inheritance strongly supports the concept of reusability i.e. newly created class reuses the properties of already existing ones. Access specifier decides the way in which the base class member will be inherited by the derived class. There are many ways to achieve inheritance single, multiple, Hierarchical, Multilevel, Hybrid. Whereas our main topic of discussion is the difference between single and multiple inheritance. In single inheritance, we do have only one base class which is inherited by … [Read more...]
