Sample C Code
The following C code performs a simple form of delta encoding and decoding:
void delta_encode (char *buffer, const unsigned int length) { char delta = 0; char original; unsigned int i; for (i = 0; i < length; ++i) { original = buffer; buffer -= delta; delta = original; } } void delta_decode (char *buffer, const unsigned int length) { char delta = 0; unsigned int i; for (i = 0; i < length; ++i) { buffer += delta; delta = buffer; } }Read more about this topic: Delta Encoding
Famous quotes containing the words sample and/or code:
“All that a city will ever allow you is an angle on it—an oblique, indirect sample of what it contains, or what passes through it; a point of view.”
—Peter Conrad (b. 1948)
“Motion or change, and identity or rest, are the first and second secrets of nature: Motion and Rest. The whole code of her laws may be written on the thumbnail, or the signet of a ring.”
—Ralph Waldo Emerson (1803–1882)
