OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career. 

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
