Difference between Top down approach and Bottom up approach.

Difference between Top down approach and Bottom up approach.


Top Down approach:- When we know the application that we are going to make and we make some modules according to that application, that modules will be used in that application.
It is known as top-down  approach.
eg:- Banking application


Bottom Top (up) approach:- When we don't about application and we make a modul or something that can be fitted in any applications. It is known as bottom-top approach.
eg:- Finance calculator 
A finance calculator can be used in banking application.


C :- printf
C++:- cout


Note:- Both approach Top-Down and Bottom-Top have no relation with language.
