Re: High Score File I/O

I am trying to save the high scores of a game I made. Now Im stumped
on trying to search through the file. Should I use a string, array,
or one of the STL containers to manipulate the information read from
the file?
I have tried the
stringname.find("Name");
This only returns the first occurence, and doesn't look for other
occurences.
I got better results just using
if(Name[i] = = NewName)
The file is a simple record like so:
Name wins loses //where wins and loses are int's
Bob 1 0 //example of format
Its to be like an old Pac-Man game record keeper.
I want to convert the name into lowercase and check to make sure only
one name is present in the file. If more than one name erase the
others otherwise check to see if WinsOnFile < CurrentWins.
If so record the new high score to the appropriate name.
This will only hold 10 high scores for different people.
Any thoughts would be helpful,
thanks
One easy way is to use a std::map. std::map has the advantage that if you
use code like this:
std::map<std::string, MyClass> Data;
Data["bob"] /*...*/
If "bob" doesn't already exist in the map, it will add it. Otherwise it
will refer to the one that already exists. For simplicity sake lets say you
were just recording number of wins.
std::map<std::string, int> Scores;
std::string Name;
int Wins;
/* Read name and Wins from file */
Scores[name] += Wins;
Now if there are 20 "Bob"s in the file, they will be added to one Score for
wins.
Things to do:
1. Convert name read to lowercase.
2. Store a structure or std::pair to represent wins and loses and not just
loses.
