};
class data2
{
    int c,d;
    public:
        void get2();
        friend void sum(data1,data2);
};

void sum(data1 a1,data2 a2)
{
    cout<<a1.a+a2.c<<endl;
    cout<<a1.b+a2.d<<endl;
}
main()
{
    data1 a;

    a.get1();
    b.get2();
    sum(a,b);
}
void data1::get1()
{
    cout<<"Enter value for a: ";
    cin>>a;
    cout<<"Enter value for b: ";
    cin>>b;
}
