int point::sum(int a,int b);
this means that you should give two values at the function.

s = D.sum(int a,int b); should be written like this: s = D.sum(a,b); where a and b were previously declared.

In the way you are using a and b in point::sum(), I suggest to modify it in this way:

int point::sum()
{
cout << "enter any 2 integers";
cin >> x >> y;
return(x+y);
}

so You can call the function without any argument: s = D.sum();
