/*It is optional to reimplement a virtual function it is not necessary to
* Reimplement it the child class can also use it like a normal function
* Hum virtual isliye likhte hain function k sath taake agr hum koi new class
* banayen aur usme humain parent k function ko change krke use krna ho toh humain parent me
* changes nah krni paren hum parent walay ko override kr len
* Agr Dog class me AVirtual wala function hata den toh b uske pass wo function mojud hoga
* aur uski implementation animal class wwali hogi jese normal cases me hota ha*/
