Question

Basically, i want to read highscores from a file and check if the user has scored enought points to be on the scoreboard. I’m trying to do it like this:

string initials[10];
int scores[10];

//load txt
ifstream highscores("highscores.txt");
if(highscores.is_open())
{
   while(highscores.good())
   {
    for(int x=0;x<10;x++)
    {
        getline(highscores,initials[x],' '); 
        highscores >> scores[x];
    }
   }

    }

the initials are only 3 chars long, so i could implement a 2 dim. array but i wanted to try it with strings. It shows that i mad one string of size 10. How should i write it so it will work with 10 arrays instead of 1? (I know i could make 10 arrays naming them from array1.. to 10, looping through them sound much better. The highscores file is just a set of 10 initialas AAA,BBB etc. and some scores.

Example of highscores.txt:

AAA 5000
BBB 4000
CCC 3000

Use std::map to hold initials and associated score. For example:

int main()
{
    // Map is keyed by initials.
    std::map<std::string, int> scores;

    std::ifstream in("highscores.txt");
    if (in.is_open())
    {
        for (;;)
        {
            std::string line;
            std::getline(in, line);

            if (!in.good())
            {
                break;
            }

            const size_t space_idx = line.find(' ');
            if (std::string::npos != space_idx)
            {
                // The initials are everthing before the space.
                // Score everything after the space.
                scores[line.substr(0, space_idx)] =
                    atoi(line.substr(space_idx + 1).c_str());
            }
        }
        in.close();
    }

    // Check who has achieved required score.
    for (std::map<std::string, int>::iterator i = scores.begin();
         i != scores.end();
         i++)
    {
        if (i->second > 3500)
        {
            std::cout << i->first << "\n";
        }
    }
    return 0;
}
