WebSep 24, 2006 · There's a classic hash function to hash strings, where MULT is defined as "31": //from programming pearls unsigned int hash (char *ptr) { unsigned int h = 0; unsigned char *p = ptr; int n; for (n = k; n 0; p++) { h = MULT * h + *p; if (*p == 0) n--; } return h % NHASH; } It looks like this code was probably mis-transcribed. WebMay 20, 2024 · A hash table uses a unique key for identifying the storage location of the data it stores. Hash table finds the key dynamically and will not generally stores the key itself. Whenever a new data has to be entered, then and there a key is determined and using this key, a location will be decided for storing this data. soul fries
