think about how to ask it in a clear and unambiguous way.
To add onto this, I personally learn best by example, so when posting questions I try to give simple examples that show what I'm trying to do.
For instance in this case you could have given the below example:
1 2 3 4 5 6 7
// I want to do something like this:
cout << a_space;
// and have it do the same thing as if I did this:
cout << " "; // (a blank space)
// how can I do this?
