Mr. Ab Surd would like to enter the wonderful world of computer graphics, but he is unfortunately trapped in a time warp, and the available computer equipment can only display text. Mr. Surd believes, however, that beautiful art can be created using text characters, if only the artist is sufficiently determined, so he sets out to write a simple ``ASCII art'' program. He begins by creating a top-down design and starting to implement it in C++, but before he can finish implementing it (i.e., writing all the code in the function definitions), he is called away by the demands of his position as Galactic Intertemporal Coordinator. Your job in this assignment is to help Mr. Surd out by filling in the gaps in his C++ program.
