This one has to be my final year project of my Bachelor's degree in computer science.The project was to develop a Fuzzy Expert Taxation System using C# and C++.But my main problem was that there were no inference engines or shells available for my project in C.Also it required a lot of meetings and interactions with Income Tax department officials which was very difficult to manage because of their timings since I also had to attend classes.So the deadline pressure was immense but in the end I some how managed to complete it.
