Hash Table String value

[aeck]

I am trying to make a hashstring function that:
sum the ordinal values of the characters of the variable multiplied by their position in the string (1-indexing), then taking the modulo by TABLESIZE.

ie. The variable ABC = (65 * 1 + 66 * 2 + 67 * 3) % TABLESIZE




The output I am trying to get is:

   VAR BORAMIR = 25	
   VAR LEGOLAS = 101	
   PRINT 	BORAMIR IS 25
   BORAMIR ++	
	
   PRINT LEGOLAS	LEGOLAS IS 101
   PRINT GANDALF	GANDALF IS UNDEFINED
   PRINT BORAMIR * 2	BOARAMIR * 2 IS 52

So far, my output is:

Start
    BORAMIR = 16
    LEGOLAS = 19
    GANDALF = 93
    BORAMIR * 2 = 80

My hashstring function is :

unsigned int hashString( const string& s) 
	{
      
	  int sum = 0;
        for (int k = 0; k < s.length(); k++)
            sum = sum + int(s[k]);
        return  sum % 100; 
   }

    int main()
    {
        cout<<"Start"<<endl;

        
        cout<<"    BORAMIR = "<<hashString("Boramir")<<endl;
        cout<<"    LEGOLAS = "<<hashString("LEGOLAS")<<endl;
        cout<<"    GANDALF = "<<hashString("GANDALF")<<endl;
        cout<<"    BORAMIR * 2 = "<<hashString("BORAMIR * 2")<<endl;

I am assuming I am using the wrong table size? I am not sure how to determine the table size for this problem? Any suggestions would be greatly appreciate!

you forgot to add multiplication for each term of sum
sum = sum + int(s[k]) * (k+1);

i'm not familiar with hash tables so I don't know what tablesize means

You might also need a second ( const int ) parameter in the hashString function to accommodate the table size instead of hard-coding it as 100.
