I want to write it with c language....I was thinking of opening the file in append mode and run a loop with counter with every '{' opening braces...the loop will give '\t' (tab) for every opening brace and in the next opening brace the counter will increase i.e there will be 2 tabs like this.....is the idea correct? or will I have to do by a different method? i will do the program in devc++ IDE.

@aritra yeah. Good for you. But you still have to present more. We are not your personal coding service. Hashnode is a discussion platform with focus on conversation. We expects subjective and opinion based questions.

You should rework your question and add approaches you came up with, asking what pros/cons we think they have and how you could go on using them.
