c++ open source project recommend [closed]

Question

I have learned c++ about three years and I have not used c++ in an actual project. I only used it to write some small program and example, I have read many books about c++ and algorithm, "c++ primer", "effective c++" "exceptional c++" "c++ common knowledge" " introduction to algorithm" ..., so I want to use it in an open source project to improve my c++ ability and enforce the knowledge base on books.

Answer 1

There are many. My suggestion would be to pick a project where you would be a user too. Then you'll have a better stakeholding in the results.

Answer 2

You mentioned in one of the comments above that you are interested in database related programming, you might want to check out the poco project, which is a fairly advanced collection of libraries:

Next generation C++ class libraries for network-centric applications.

The POCO C++ Libraries (POCO stands for POrtable COmponents) are open source C++ class libraries that simplify and accelerate the development of network-centric, portable applications in C++. The libraries integrate perfectly with the C++ Standard Library and fill many of the functional gaps left open by it. Their modular and efficient design and implementation makes the POCO C++ Libraries extremely well suited for embedded development, an area where the C++ programming language is becoming increasingly popular, due to its suitability for both low-level (device I/O, interrupt handlers, etc.) and high-level object-oriented development. Of course, the POCO C++ Libraries are also ready for enterprise-level challenges.

Features

• threads, thread synchronization and advanced abstractions for multithreaded programming
• streams and filesystem access
• shared libraries and class loading
• powerful logging and error reporting
• security and encryption
• network programming (TCP/IP sockets, HTTP client and HTTP server, FTP, SMTP, POP3, etc.)
• XML parsing (SAX2 and DOM) and generation
• configuration file and options handling
• SQL database access (ODBC, MySQL, SQLite)

Some time ago, there was also some talk on sourceforge about possibly implementing an ODBMS using poco (see here).
