Question

I have just learnt about dynamic memory allocation, After seeing a lot of videos and reading many examples, I understood what it is.
But now,how and where to use excatly?

Answer 1

Dynamic memory allocation is mainly used while working with pointers.

If you declare a pointer, but you don't want it to point at other variable, then you can use dynamic memory allocation to use that pointer.
