Last array element in a row and first element in the next row having the same pointer

I was working on a college assignment that required me to get a mathematical equation related to array pointers, I wrote the following code to display the pointers of all elements:

Code to the left, output to the right.

It was all smooth until I decided to convert the addresses to decimal to make my calculations easier, I used the following line of code:

size_t D = reinterpret_cast<size_t>(&X);

Once I did, somehow the last element in a row and first element in the next row returned the same address:

Marked in red

Even after I removed that line and restored my code to it's previous state, the specified elements still return the same address. I thought it might be a weird Visual Studio behavior and I tried restarting it, but the issue wasn't fixed. I'm wondering how this happened and how it can be fixed, it doesn't make sense.

The size of your array was changed to Arr[5][4]. It won't return an error or warning as, they are all valid pointers to the 'one past the end' element of an array.
