Arrays of mpz_t

[David McKen]

I can confirm that the C++ wrapper mpz_class works both with the new 
operator and with vector<>. Failing that (and assuming you want to use 
C) you can do the following:

unsigned num_elements = 1000;
mpz_t * my_array;
my_array = malloc(sizeof(mpz_t) * num_elements);
//Initalize
//Use
//Clear
free(my_array);

Just curious do you know about the mpz_array_init function? It imposes 
some limitations but it may be useful.
