Pointer to an Array - GeeksforGeeks
Here, p is pointer to 0 th element of the array arr, while ptr is a pointer that points to the whole array arr. The base type of p is int while base type of ptr is 'an array of 5 integers'.; We know that the pointer arithmetic is performed relative to the base size, so if we write ptr++, then the pointer ptr will be shifted forward by 20 bytes.; The following figure shows the pointer p and ptr.

c++ - Pointer arithmetic in 2D array - Stack Overflow
If you then derefernce that pointer, the address of the first element in the first array is returned. In both cases that pointer will have the same address but the pointers will be of very different types. In the first case it is a pointer to array of int [5] and in the second case a pointer to int. See C11 Standard - 6.3.2.1(p3) –
