Why *must* an overriding of a virtual method have the same argument signature as that of its ancestor? What happens if it doesn't?
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.

- Why *must* an overriding of a virtual method have the same argument signature as that of its ancestor? What happens if it doesn't?
