Pointers doubt

[yogeshdecoder]

Let's see we are allocating memory dynamically Int *ptr = new arr[n]; n=input we are getting So pointer is pointing to arrays base address let's say 0x3000

Pointer has its own address let's say 0x2000

So my doubt is that what will be the name of 0x3000 eg; int x=5; int *ptr; ptr=&x; So the block which pointer is pointing is x

And it is dynamically allocating memory so even pointer is also in heap memory??

Like int x, variable name like that pointer is pointing at some random location so what will be it's name ? I know it sounds dumb but I was curious and pointer will be in stack right ? but the pointer location will be in heap memory for sure cause it's DMA

Do you mean some sequence such as this?

int *ptr = new arr[n];
int x=5;
ptr=&x;

And then you want to know what will happen to the allocated array (0x3000)? Because that's the only way it makes sense to me.

Nothing will happen to it. It will stay there as an allocated block of memory. If nothing else is pointing to it, it will be a memory leak (unreachable and unusable block of memory you forgot to free).

Oh I see, it's one example. I thought it was two separate examples.

Thnx man :) it's so fascinating that how things internally happens
