А в чём проблема?

#include <stdio.h>

typedef int (*reduce_function)(int x, int y);

int reduce(reduce_function f, int z, int *xs, int *xe)
{
    return xs == xe ? z : reduce(f, f(z, *xs), xs + 1, xe);
}

int r(int x, int y)
{
    return x * 2 + y;
}

int main()
{
    int xs[] = {1, 2, 3};
    int v = reduce(r, 4, xs, xs + 3);
    printf("%d\n", v);
    return 0;
}
