Joarder sir's presentation.: some info

Joarder sir said some particular things about tomorrow's presentation.
1. Just make a program which generates a hash, using specific algorithm.
2. Make sure that you do save the presentation in teacher's pc before he comes. He won't waste a minute in this saving presentation thingy. Presentations will start sharp at 9.
3. Make sure that you do understand the hashing process clearly.
4. Presentation should include the implemented code's executable file, no need of using extra complex algorithm or process.
5. He wishes you all best of luck.
