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:int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000 <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000 )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}
