when i allocate a vector to a pointer with the new operator and allocate again another vector with different dimensions to the same pointer does the memory from the first vector get totaly freed?

Indexing into the vector is slightly more expensive than indexing into an array, though, as the internal mechanism for indexing into the vector involves pointer arithmetic.

Indexing an array involves *exactly* the same pointer arithmetic as indexing a vector.
