The hash class is default constructible, which means that one can construct this object without any arguments or initialization values. It is used to get the hash value of the argument that is being passed to it. If the argument doesn’t change, the value doesn’t change either.
template <class T> struct hash;
Syntax to create object:
hash<class template> object-name
Member functions: This Hash class only has one member function:
- operator(): It returns hashed value for given argument.
Below is the implementation of the hash class:
String hash values: 4457761756728957899 Bitset 10101 hash value: 17123654466142159564 Vector
hash value: 16935082123893034051 Char hash values: 97
