value_type
вы берёте опять же из явно указанного шаблона. Если вы поменяете тип P
например на Point<double>
, то и тип X
придётся изменить.typedef Point<int> MyPoint;
MyPoint P = {1, 2};
MyPoint::value_type X = P.x;

I would say that a checksum is necessarily a hashcode. However, not all hashcodes make good checksums.
A checksum has a special purpose --- it verifies or checks the integrity of data (some can go beyond that by allowing for error-correction). "Good" checksums are easy to compute, and can detect many types of data corruptions (e.g. one, two, three erroneous bits).
Checksum functions are related to hash functions, fingerprints, randomisation functions, and cryptographic hash functions. However, each of those concepts has different applications and therefore different design goals. Check digits and parity bits are special cases of checksums, appropriate for small blocks of data (such as Social Security numbers, bank account numbers, computer words, single bytes, etc.). Some error-correcting codes are based on special checksums that not only detect common errors but also allow the original data to be recovered in certain cases.
Choosing a color palette
Your app's color palette may be defined by using a custom palette suited to your brand, such as monochromatic, black and white, full color, or neutral. Alternatively, you may use the material design color palette. All color palettes should include sufficient contrast between different UI elements.
