Given an array of pointer to ints, how can i copy a refernce to the array? int *array[100]; int *i i = array; i[0] = blah blah; I''m sure you get what i mean but i get the following e error C2440: ''='' : cannot convert from ''int *[100]'' to ''int *''

As an array of pointers is (basically) a pointer to a pointer:

int *array[100];

int **i = array;

...

I'm not quite sure why you are asking about a "reference", though in your example you are using pointers, though.

If i use the above technique i can assign my new variable to the array but i cannot access it like an array :

i[5] = xxx;

is it possible to do this?

array is a pointer to pointers.

i is a pointer to ints.

Thus, they are not the same type.

If you declare i like Lektrix said, they are of the same type and then you could use i like you want.
