Actually there's a little more than that. The book says something
like:
With this code example
int main()
{
int x;
std::cin >> x;
std::cout << ("hello world!" + x) << std::endl;
}
the input
4
produces
o world!
on the standard output.
Now can you see why one might want to check that the example produces
particular output? In this case, the expected output is actually
contained in the documentation.
