I have to do enhancements to an existing C++ project with above 100k lines of code.
My question is How and where to start with such projects ?
The problem increases further if the code is not well documented.
Are there any automated tools for studying code flow with large projects?
Thanx,
Creating a comprehensive scope, a well-balanced and highly skilled team, and a realistic timeline are the most important steps to building a successful project. These three points will be your project's North Star going forward.
Use Source Control before you touch anything!
There's a book for you: Working Effectively with Legacy Code
It's not about tools, but about various approaches, processes and techniques you can use to better understand and make changes to the code. It is even written from a mostly C++ perspective.
