Sliding

The document contains a C program that implements a sliding window protocol for transmitting frames. It prompts the user for the window size and the number of frames to transmit, then simulates sending the frames and waiting for acknowledgments. The program outputs the frames being sent and indicates when acknowledgments are received after every 'w' frames.
