Answer 2

Use Swig, it allows you to generate code for several languages ​​that calls any C / C ++ function. http://www.swig.org/

Answer 3

... c/++, , java, . , , .

Answer 4

.

, C . Python:

os.system("myccode -v args etc")

, - , . , .

Each language has its own mechanism for calling C in a single process. Python, for example, has a C API, and you can create your C code in a Python extension. This allows a very tight integration, but it works better both when learning the C API and carefully writing code so that there is no memory leak.

Python also provides ctypes , which can call the C DLL. This is slightly simpler than the full C extension, but does not provide all the integration options.
