String hash function in c
WebThe FNV1 hash comes in variants that return 32, 64, 128, 256, 512 and 1024 bit hashes. The FNV-1a algorithm is: hash = FNV_offset_basis for each octetOfData to be hashed hash = hash xor octetOfData hash = hash * FNV_prime return hash Where the constants FNV_offset_basis and FNV_prime depend on the return hash size you want: Web传递Hash 这需要复制构造函数， 您没有一个(或者是botch，私人或明确的) 所以，通过参考. 进行Hash void topWords(Hash const& t, std::string const& word, std::string* topA); 另外， string[]不是C ++中的类型; 不要使用using namespace std;
