if i do : int *i; i = new int [5]; how do i increase or shrink the array without having to start copying all the data into a new array and swapping pointers?

You can''t do it without copying and reallocation. The easiest solution would be to use the standard vector which handles all that dirty work for you.

Note: You can resize arrays created in the C-style way, with malloc or calloc, by using the function realloc. However, you should never mix calls to new/new[]/delete/delete[] with calls to malloc/calloc/realloc/free.
