In my code, I have the following:
ostream_iterator<double> doubleWriter(cout, " ~ ");
// ...
*doubleWriter = 1.1;
doubleWriter++;
*doubleWriter = 2.2;
*doubleWriter = 3.3; // shouldn't 2.2 be overwritten?
doubleWriter++;
*doubleWriter = 44.2;
cout << endl << endl;
I expected it to output this:
1.1 ~ 3.3 ~ 44.2 ~
Instead, the output was this:
1.1 ~ 2.2 ~ 3.3 ~ 44.2 ~
Why does this happen? It would seem to me that I overwrite 2.2 and stick 3.3 in its spot, since I didn't increment. Is incrementation an optional step?
