Data file formatting - Greatest to Least

[facebookisgayyy]

I have a Trivial Pursuit type program. The following program is the program I use as a leaderboard.. so when it runs it pulls the scores of all of those users that have played and shows them on the screen. How would I order the scores in greatest to least?

for example, running the program now will print something along the lines of

BMT 9
JAS 3
FKE 6
TLO 4

while I'd like it to print

BMT 9
FKE 6
TLO 4
JAS 3

    string name;
    int num, n=1;
    ifstream infile;
    infile.open("H:\\files\\score.txt");
    string Name[50];
    int Num[50];
    
    infile >> name;
    infile >> num;
    while(!infile.eof())
    {
    infile >> Name[n];
    infile >> Num[n];
    cout << Name[n] << " \t" << Num[n] << endl;
    n++;
    }
    
    system("PAUSE");
    return 0;
    }

I figured it out, I hope this code helps whoever needs it

//Brandon Thomas
#include<iostream>
#include<fstream>
#include<iomanip>
using namespace std;
int main()
{
    string name;
    int num, n=0;
    ifstream infile;
    infile.open("H:\\files\\score.txt");
    string Name[50];
    int Num[50];
    
    infile >> name;
    infile >> num;
    while(!infile.eof())
    {
     infile >> Name[n];
     infile >> Num[n];
     cout << setfill(' ') << setw(5) << Name[n] << setw(5)<<Num[n]<<endl;
     n++;
    }
    
    int temp;
    string tempName;
    for(int y=0; y < n; y++)
    {
     for(int k =0; k < n -1-y; k++)
     {
      if(Num[k]<Num[k+1])
      {
       temp = Num[k];
       Num[k] = Num[k+1];
       Num[k+1] = temp;
       tempName = Name[k];
       Name[k] = Name[k+1];
       Name[k+1] = tempName;
      }
     }
    }
      cout << endl<<endl;
      cout << "Sorted Array" << endl<<endl;
      for(int i = 0; i < n; i++)
      {
       cout << setfill(' ') << setw(5) << Name[i] << setw(5)<<Num[i]<<endl;
      }
    
    system("PAUSE");
    return 0;
}

The easiest solution is to pack all the names and numbers into a struct like this:

struct score {
    string name;
    int num;

    score(string n, int x) : name(n), num(x) {}
};

Then you put all the information in a random-access container like vector:

vector<score> data;

data.push_back(score("Name1", num1));
data.push_back(score("Name2", num2));
...

Now you just need to sort this vector using the std::sort algorithm you get with the <algorithm> header. (see http://www.cplusplus.com/reference/algorithm/sort/)
