Thread: I'm stupid, heres why(it doesnt work!)

I'm new at programming(I started about... an hour ago?), and this dumb little program i tried to make doesn't work... TELL ME WHY!

#include <iostream.h>
int main()
{
int a,b,c,d,e,f,g,h;
cout<<"Welcome to the Age Finder! What year is it now?";
cin>>a,b,c,d;
cout<<"Ah, yes! Now I remember...The year is "<<a,b,c,d;
cout<<" Speaking of the year, what year were you born in?";
cin>>e,f,g,h;
cout<<" Wow..."<<e,f,g,h;
cout<<" That means you must be ";
cout<<(a,b,c,d-e,f,g,h);
cin.get();
return 0;
}
