Frame program trouble
Author
I'm learning from a book recommended to me called Accelerated C++. The 2nd chapter is about making a framing program. I figured most of it out but one of questions that the author uses at the back of the chapter is:
"The framing program writes out mainly black lines that separate the borders from the greeting one character at a time. Change the program so that it writes all the spaces needed in a single output expression."
I don't quite understand how to do that. I'm probably just tired but help would be nice.
