You can use:
// The struct that will hold the pointer and the magic number
struct data {
void *other_struct_ptr;
unsigned int magic_number;
};
// Declare my array
struct data array[N];
Where N is the size of your array. Now just fill your data into the array. For example:
array[0].other_struct_ptr = NULL; // I used NULL for simplicity
array[0].magic_number = 0xDEADC0DE;
array[1].other_struct_ptr = NULL;
array[1].magic_number = 0xCAFEBABE;

Define a struct like this:
struct data_t
{
void *pointer;
int magic_number;
};
Then use following array:
data_t values[100]; //100 is just for example
Or maybe you need such 2D array:
data_t values[100][100]; //100s are just for example
