double Loading[MAX_AGE][NUM_GENDERS] = {0};
//...
void PopulateLoading Array(double **Loading, size_t MaxAge,
size_t NumGenders)
{
size_t Age, Gender;

for(Age = 0; Age < MaxAge; Age++)
{
for(Gender = 0; Gender < NumGenders; Gender++)
{
**(Loading + Age * MaxAge + Gender) = CalcLoading(Age ,
Gender);
cpl qs:

1. why this (Loading + Age * MaxAge + Gender) instead of
(Loading + Age * NumGenders + Gender)?

2. sinze Loading is (double **), does ptr arithmettic
calcullate sizeof(double) elementt or wrong sizeof(double *) elementt,
i not understend? fe. Loading + 1 - this calcullate
Loading + sizeof(double *) .. or Loading + sizeof(double)? ??
