Solution 2

I am confused.

How can you tell a persons Gender from their name?
Short of going back and asking them there is no way of obtaining this.
I think you would have serious problems of accuracy regardless of the approach taken.

Dalek, those are Muslim names, they are well identified by first name. It was already a similar discussion about Indian names. Still, I argued: what if a foreign person gets Indian citizenship? One very interesting CodeProject author from Southern India explained that they don't have family names, so when this guy immigrated to USA, he created one composed from ancestor's names. His official USA "last name" is approximately the length of the present comment...

I understand.
I still cannot see how you could possibly infer their gender.
Genders change, quite regularly sometimes, dependant on mood or situation.
But even if you took the dominant gender, it is still not indicated by name is it?

I have known some very masculine women and some very feminine men, so the gender is not even indicated by the sex of the individual.
As I say, you would have to ask them one at a time.

I agree 100% with Dalek. Unless you know the gender, you'll never be 100% accurate.

Consider the following table, with the following columns:
Name Surname Gender Age
If the records are stored in a data table, this could be easily done by:

C#

DataView dv = new DataView(dtSource);
dv.RowFilter = "Gender = 'M'";
int maleAge = 0;
for (int i = 0; i < dv.Count; ++i)
{
       maleAge += Convert.ToInt32(dv[3]); //where 3 is the person's age
}
double maleAvgAge = maleAge / dv.Count;

dv.RowFilter = "Gender = 'F'";
int femaleAge = 0;
for (int i = 0; i < dv.Count; ++i)
{
       femaleAge += Convert.ToInt32(dv[3]); //where 3 is the person's age
}
double femaleAvgAge = femaleAge / dv.Count;
