Question

Following java code returns hash code of a string.

String uri = "Some URI" public int hashCode() {     return uri.hashCode(); } 

I want to translate this code to c++. Is there any function availabe in c++ or an easy way to translate this.

Answer 1

In C++03, boost::hash. In C++11, std::hash.

std::hash<std::string>()("foo"); 

Answer 2

Boost provides a hash function:

boost hash

#include <boost/functional/hash.hpp>  int hashCode() {     boost::hash<std::string> string_hash;      return string_hash("Hash me"); }
