Why isn't this a Contradiction? i.e What did I understand wrong?
The book "Thinking in C++(V2)" gives something like the following example:
Code:
int main()
{
ifstream in("a.cpp");
while(in.get(*cout.rdbuf()))
in.ignore();
return 0;
}
It compiles and works correctly.
But my <streambuf> file says:

But the code compiles and runs as expected.
Isn't cout's streambuf being written on in the example ?
Or..more likely...what punchline am I missing ?
