- CUnit is a light-weight library that allows programmers to test their C code. Test results can be browsed in multiple formats or built-in interfaces.
- Check is a unit test framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so Check can catch both assertion failures and code errors that cause segmentation faults or other signals. The output from unit tests can be used within source code editors and IDEs.
- Checker is a debugging tool suite which is used to find memory errors at runtime. 'Checker' can help find bugs that standard tools cannot always find. The best example is memory leaks. A memory leak is a zone of memory, allocated with malloc that is not used anymore. So the memory allocated is lost. This means you program needs more memory and runs slower, since your OS might have to start swapping. It detects bad memory accesses such as: reading uninitialized memory, writing in a freed zone, writing or reading outside of a memory block, and using NULL pointers. This is particularly useful for big programs with many functions. Checker maintains bitmaps to keep track of the status of each byte of memory. The status can be writable, readable, both, or none. When memory is allocated, the new memory becomes write-only: you are not allowed to read it because it has not been initialized. But when you you write to this new block, those bytes become readable and writable. When the block is freed, the bytes become unreadable and unwritable. Red zones are unreadable and unwritable memory, so that each access to a red zone produces a warning.
- ANSI Common Lisp is a high-level, general-purpose programming language. GNU CLISP is a Common Lisp implementation by Bruno Haible of Karlsruhe University and Michael Stoll of Munich University, both in Germany. It mostly supports the Lisp described in the ANSI Common Lisp standard. It runs on most GNU and Unix systems (GNU/Linux, GNU/Hurd, FreeBSD, NetBSD, OpenBSD, Solaris, Tru64, HP-UX, BeOS, IRIX, AIX, Mac OS X and others) and on other systems and needs only 4 MB of RAM. The user interface comes in English, German, French, Spanish, Dutch, Russian and Danish, and can be changed during run time. GNU CLISP includes an interpreter, a compiler, a debugger, CLOS, MOP, a foreign language interface, a socket interface, i18n, fast bignums, arbitrary precision floats and more. An X11 interface is available through CLX, Garnet, CLUE/CLIO. GNU CLISP runs Maxima, ACL2 and many other Common Lisp packages.
- CodeLite is a cross platform IDE for the C/C++ programming languages. Particular features are its excellent code-completion and refactoring. It has generic support for compilers, with built-in support for GCC and Clang. It supports debugging with both GDB and LLDB. It comes with many plugins, including ones for Git and Subversion, qmake, CMake, cscope and Cppcheck. Since version 13.0 it also includes the RAD plugin wxCrafter.
- Condenser is a tool for finding and removing duplicated Java code. Unlike tools that only locate duplicated code, Condenser is also able to automatically remove duplicated code where it is safe to do so.
- 'CrocoPat' is a tool for querying and manipulating relations. It is easy to use because of its simple query and manipulation language based on predicate calculus and its simple file format for relations. It is efficient because it internally represents relations as binary decision diagrams, a data structure that is well-known as a compact representation of large relations. CrocoPat is general, because it manipulates not only graphs (i.e. binary relations), but n-ary relations.
- Crossroads Load Balancer
- Crossroads is a load balance and failover utility for TCP-based services. It is a daemon program running in userspace and features extensive configurability, polling of backends using "wakeup calls", detailed status reporting, "hooks" for special actions when backend calls fail, and more. It is service-independent; it is usable for HTTP(S), SSH, SMTP, DNS, etc.
- CxxTest is a JUnit/CppUnit/xUnit-like framework for C++ that doesn't require RTTI, member template functions, exception handling, or any external libraries (including memory management, file/console I/O, or graphics libraries). It is distributed entirely as a set of header files which makes it extremely portable and usable.
- 'DBG-Client' is the client for the DBG debugger and profiler for the PHP programming language.
