Receiver.c

/**
  * This code snippet demonstrates a simple receiver function for a communication protocol,
  * likely related to some form of Automatic Repeat reQuest (ARQ) method. The receiver simulates the reception of frames,
  * checking for corruption based on an error probability, and sends acknowledgments for the received frames.
