Explain you in much simpler word then technical language .. Suppose you have a class like below class A { string Name; string Age; } now you have coded class A but what if you want to Code a Class that hase Same Functionality as A and Additional functionality too. ??? so will you write the above code again to get same functionality as Class A in class B ..???? of course no !! in this case inheritance can help you to Import the Functionality of Class A into Class B.. it means it can Extend the Functionality . Class B:A // Inherit Will Import those two variables in Class B { //Just add Extra Members that are not In A string Age; string Address; } so By Look its Looks that we have added only Two New Variable in Class b but While accesing the Class B We can use 4 Variables that's in class A and Class B too :) if my answer helps you then check "Do you like this answer" check box :)
