What is the difference between IPC and RPC?

RPC is a penal code applicable in the State of Jammu and Kashmir. Indian Penal Code (IPC) is not applicable there under Article 370 of the Constitution of India, which gives an autonomous status to J&K. The code was introduced during the reign of Dogra dynasty with Ranbir Singh as its ruler and therefore named as Ranbir Penal Code (RPC).
