So I finally finished writing a program to build a maze using disjoint set (I just learned it =P). Anyway as I was writing my program, I was under the impression that I could start from the end of the maze and I could climb up to the parent node … |

After tackling with this function for almost the whole day, I still cannot figure out why this code isn't working. My BTNode has three pointers(left, right, and parent). I went through this code on paper and it seems to work fine, but it does not work fine during execution. I … |

I recently needed to add member functions like these into my class [CODE]istream& read(istream&) ; ostream& print(ostream&); [/CODE] I am a little confused on how to actually call these functions within my class.

So I am creating a program for a class that reads in from a file the appointments. The file has this format Date,Subject,Start Time,End Time,Location,, The interesting thing about the file is that it does not contain the same appointment (same name, location, and time) more than once. For example: … |
