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:

    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)

    Wise Draco comes, deep in the midnight roll
    Of black artillery; he comes, though late;
    In code corroborating Calvin’s creed
    And cynic tyrannies of honest kings;
    He comes, nor parlies; and the Town, redeemed,
    Gives thanks devout; nor, being thankful, heeds
    The grimy slur on the Republic’s faith implied,
    Which holds that Man is naturally good,
    And—more—is Nature’s Roman, never to be
    scourged.
    Herman Melville (1819–1891)
