copied!<p>For writing binary, the trick I have found most helpful is to store all the binary as a single array in memory and then move it all over to the hard drive. Doing a bit at a time, or a byte at a time, or an unsigned long long at a time is not as fast as having all the data stored in an array and using one instance of "fwrite()" to store it to the hard drive.</p> <p>size_t fwrite ( const void * ptr, size_t size, size_t count, FILE * stream );</p> <p>Ref: <a href="http://www.cplusplus.com/reference/clibrary/cstdio/fwrite/" rel="nofollow">http://www.cplusplus.com/reference/clibrary/cstdio/fwrite/</a></p> <p>In English:</p> <p>fwrite( [array* of stored data], [size in bytes of array OBJECT. For unsigned chars -> 1, for unsigned long longs -> 8], [number of instances in array], [FILE*])</p> <p>Always check your returns for validation of success!</p> <p>Additionally, an argument can be made that having the object type be as large as possible is the fastest way to go ([unsigned long long] > [char]). While I am not versed in the coding behind "fwrite()", I feel the time to convert from the natural object used in your code to [unsigned long long] will take more time when combined with the writing than the "fwrite()" making due with what you have.</p> <p>Back when I was learning Huffman Coding, it took me a few hours to realize that there was a difference between [char] and [unsigned char]. Notice for this method that you should always use unsigned variables to store the pure binary.</p>
