@chandnigandhi: Since you are talking about a mini project, I would suggest you start out by thinking about some problem relevant to your daily life, and then developing a solution to that problem -- it makes it a lot more enjoyable!

Code a program that would replace all words (that are same) in a text file by a given word by user. It proves to be quite handy sometimes
