Is there a difference between the following two lines:

const int i = 0;
int const i = 0;

apparently, I was told they are different, so I wanted to know the difference.

They're exactly the same, the difference with the positioning of "const" comes into play when you use pointers.

const int* is a constant pointer to integer data, that means you cant change the pointer itself to point to something else.

int* const is a pointer to constant integer data, which means you can change the pointer, but you can't change the data it points to.

That would be the other way around.

const int* -> a (variable) pointer to constant integer data
int* const -> a constant pointer to integer data

The trick is reading from right to left.
