GitHub is where people build software. Source code of The Standard C Library, by P. C at master · dougct/c-standard-library memcpy just aids your task by providing you with a ready to use API call, instead of having you to write 20 lines of code for a petty thing. The implementation is a while loop that copies one byte at a time.
