Simplest and main difference is...this two are process of solving program........
So in top down it breaks the main program in sub programs then all the sub programs are being solved then after solving it merge them all in one function to provide exact output.....so 1st we have top as a main function ok...then we break it into sub function can be taken as down...so it approach as top to down...
In the same way in c++....program is already in sub functions....it directly solve this problems and merge them together for exact output....so what is happening here that Bottom as a sub function and Up as a merge function..so it approach as bottom to up.....
....Thanks 4 reading
