modify has function from string parameter to templates...
hello, I have this function:
template <class T> unsigned int HashTable<T>::hash( const string & key ) const
{
unsigned int hashVal = 0;
// cout << key << "%";
for( size_t i = 0; i < key.size(); i++ )
hashVal = ( hashVal << 5 ) ^ key[ i ] ^ hashVal;
return hashVal;
}
how to I convert it so it works with all data types?
To format your code properly for the board, put a [/code] tag at the end of your source code, and a [code] at the beginning. Edit your post and add those (with indentation) - you're much more likely to get help if your source code is easier to read.
you can pass the hash function as a template parameter instead.
Code:template <class T, class hash = some_sensible_default> class HashTable { //... };
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
