please I need Help with Hamming code (7,4) encoding/decoding

hey guys I am doing encoding/decoding hamming code (7.4) I need a way to divide the input message (up to 255 bits) into block of 4 bits so i can apply hamming code in each block individually. I have to use simple operations to implement hamming code.

Thank you in advance

What format is the input message in? I.e., what type and size of variable do you have to work with?
