why does this loop never end

[bbathel]

     for(int i=0;i<NUMBER_OF_CARD_VALUES;i++)
           {
                if((CARD_VALUES[i]) == next_char)
                  {
                       return(true);
                  }
                
           }       
        return(false);
        
}

this loop just never ends

Check the value of NUMBER_OF_CARD_VALUES. If it is not a constant, it may have gotten changed.
