Delta Encoding - Sample C Code

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; } }

Famous quotes containing the words sample and/or code:

    The present war having so long cut off all communication with Great-Britain, we are not able to make a fair estimate of the state of science in that country. The spirit in which she wages war is the only sample before our eyes, and that does not seem the legitimate offspring either of science or of civilization.
    Thomas Jefferson (1743–1826)

    Faultless honesty is a sine qua non of business life. Not alone the honesty according to the moral code and the Bible. When I speak of honesty I refer to the small, hidden, evasive meannesses of our natures. I speak of the honesty of ourselves to ourselves.
    Alice Foote MacDougall (1867–1945)
