PYNQ provides Python APIs.  
If you want to use C, PYNQ does not provide C APIs. You can build C applications like you would for other Zynq Linux boards. You would be better posting on [Xilinx forums](https://forums.xilinx.com/) or elsewhere if this is what you want to do.  
You can call C code from Python which would allow you to work with PYNQ. More general info on this here: [https://realpython.com/python-bindings-overview/](https://realpython.com/python-bindings-overview/)
