Let me try to summarize what I *think* you're trying to do. (I haven't
been following this thread 100% thoroughly, so I might be either
repeating or misunderstanding some of what's been said.)
You have an array of structures, where each structure has a member of
type double. You want to compute the geometric mean of those N members.
That seems straightforward enough that I don't mind showing a solution
rather than a hint:
#include <stdio.h>
#include <math.h>
struct foo {
double x;
};
static double geomean(struct foo *arr, size_t count) {
double product = 1.0;
for (size_t i = 0; i < count; i ++) {
product *= arr[i].x;
}
return pow(product, 1.0/count);
}
int main(void) {
struct foo the_array[] = {
{ .x = 3.0 },
{ .x = 4.0 },
{ .x = 5.0 }
};
printf("Geometric mean = %f\n",
geomean(the_array, sizeof the_array / sizeof the_array[0]));
}
Output:
Geometric mean = 3.914868
(which is consistent with my manual calculation of the cube root of
3*4*5).
You say you want to make the function "generic". That can mean a lot of
things, but I think what you want is to have a function that can do the
same thing for an array of *any* structure type that contains a double
member.
There is no clean way to do that in C.
I can think of several not-so-clean solutions. The standard qsort()
function gives some hints about how you can operate on arrays of
arbitrary element types
You could pass a void* pointer to the initial element of the array,
along with a size_t indicating the size of a single element, another
size_t to specify the number of elements, *and* yet another size_t to
specify the offset of the double member within the structure. The body
of the function will have to do some fairly ugly pointer casts to
extract the actual data. If you do everything correctly, it should
work, but there are a number of mistakes you could make that the
compiler can't help you diagnose, because you you have to throw away
type information.
You could also wrap the entire function definition in a macro
definition, with macro parameters to specify the name of the structure
type and of the double member. You'd have to invoke the macro for each
structure type, creating a new function with a distinct name.
Or the geomean() function could take a function pointer as an argument,
where the pointed-to function returns the value of the double member.
But you'd still have to use void* pointers to refer to the array
elements.
The fact that doing this is so ugly might suggest that a change of data
structure would be appropriate. (Or conceivably a change of language,
but I'm not sure what language would handle this gracefully; I don't
think C++ would.)
If you're doing a lot of operations that have to iterate over sequences
of double values, it's going to be a lot easier if they're stored in
arrays of doubles, rather than scattered as double members of arrays of
structures.
On the other hand, that loses the coherence of using a structure to
collect all the relevant information about a given entity in one place.
Conceivably the structure could contain a pointer to the array element,
but keeping that consistent is going to be non-trivial.
