I’m having a tough time wrapping my head around this. Started going over 1D arrays and pointers and I understood all these things about it-

Suppose there’s

int a[]{1,2,3,4};

Here, a is the pointer to the first element, and has its address stored in it. We can assign a pointer like so

int* p = a

and access the elements with *p, *(p+1), *(p+2), etc…

Now with a 2D array, let’s say

int b[2][3]{1,2,3,4,5,6}

b is still the address of the first element b[0][0], b[0] and b[1] hold addresses to the corresponding 1D arrays inside b, I can do

int* p0 = b[0]
int* p1 = b[1]

so why isn’t b an array of pointers? Why can I not do

int** p = b

And stemming from the same doubt, why will this(see attached image) not work? Why does the parameter m[][] not receive the address of m[0][0], and why does m[i][j] not navigate to the expected address?

I’ve tried googling, and watched a couple of youtube videos but nothing helps with this doubt. I would really like to have a clear understanding of what’s going on here. Thanks!
