Calculating Values at Compile Time

Demo Code

#include <iostream>
#include <string>

using namespace std;

unsigned int SDBMHash(const std::string& key)
{
    unsigned int result{ 0 };

    for (unsigned int character : key)
    {/* w  w  w  .  j a  v  a  2s  .c  o  m*/
        result = character + (result << 6) + (result << 16) - result;
    }

    return result;
}

int main(int argc, char* argv[])
{
    std::string data{ "data test" };
    unsigned int sdbmHash{ SDBMHash(data) };

    cout << "The hash of " << data << " is " << sdbmHash;

    return 0;
}
