Functions problem !!!

[DeepFreeze]

hi this is my first post. I need some help...
I have the following code:

#include <iostream>

using namespace std;

int date_birth(int year,int month,int day);

int main()
{
int a=0,b=0,c=0,x=0,y=0;

cout<<"Year ",cin>>a;
cout<<"Month ",cin>>b;
cout<<"Day",cin>>c;

x=date_birth(a,b,c);
y=date_birth(a,b,c);

cout<<"x "<<x<<endl;
cout<<"y "<<y<<endl;

return 0;
}

int date_birth(int year,int month,int day)
{
int a=0,b=0;
a=year+month;
b=month+day;
return (a,b);
}

My function just return the second parameter (b).
I need both of them.

How to code a function to return more than one value???

Help please.

A function can only return one value. If you need to do more than one assignment, you'll need to pass things as pointers or references.

Thanks, helios for your quick replie.

I am going to study pointers right now.
