WebMar 12, 2024 · C++ Hash Table Implementation. We can implement hashing by using arrays or linked lists to program the hash tables. In C++ we also have a feature called “hash map” which is a structure similar to a hash table but each entry is a key-value pair. In C++ its called hash map or simply a map. Hash map in C++ is usually unordered. WebAug 12, 2010 · That checksum function actually does both jobs. If you pass it a block of data without a checksum on the end, it will give you the checksum. If you pass it a block with the checksum on the end, it will give you zero for a good checksum, or non-zero if the checksum is bad. This is the simplest approach and will detect most random errors. colog geophysics
