The program is hamming code for error detection of a 8 bit data stream. In this algorithm for error detection the number of redundant bits is considered as per the input data stream that is to be transmitted across the network. For example, 8 bits of data will have 4 redundant bits. The error is detected by parity check with the binary value at the positions of the input data stream. Here the redundant bits are sent along with the input data and this can be checked for correctness at the receiver end.
