The application is developed using VC++ My Files are of Html type

Is there any library which will do the diff opereation between two files

Answer 1

You can probably easily link diffutils into your code.

Answer 2

This depends on what types of files you are comparing. Are they text? HTML? Binaries?

Try searching this site (and Google) for 'diff', there are lots of questions and answers ranging from general how-to, to code examples, to full source code and 3rd party libraries.

Answer 3

WinMerge is a Windows differencing and merging tool. It uses diffutils, written using VC++, and it's open source.

Answer 4

You could start by looking at a couple of CodeProject articles that could be modified to generate the diff files you require:

1) Diff Tool

2) V Diff - A File Comparer with visual output
