Question

Can anyone help me with my C++ assignment on structs, arrays and bubblesort? I can't seem to get my code to work. The output should have the AVEPPG from highest to lowest (sorted by bubbesort). The output of my code is messed up. Please help me, thanks.

Here's the input.txt:

Mary 15 10.5

Joseph 32 6.2

Jack 72 8.1

Vince 83 4.2

Elizabeth 41 7.5

The output should be:

NAME             UNIFORM#    AVEPPG

Mary                   15     10.50

Jack                   72      8.10

Elizabeth              41      7.50

Joseph                 32      6.20

Vince                  83      4.20 ​

My Code:

#include <iostream>
#include <iomanip>
#include <fstream>
#include <sstream>

using namespace std;

const int PLAYERS = 25;

struct playerType
{
string name;
int uniformNum;
double averagePoints;
};

void readPlayerData(playerType[], int&, ifstream&);
void outputResults(playerType[], int);
void bubbleSort(playerType[], int);

int main()
{
ifstream in;
string filename;
playerType playerArray[PLAYERS];
int numPlayers = 0, i = 0, j = 0;

while(1)
    {
      cout << "Enter the file name: ";
      cin >> filename;
      in.open(filename.c_str());
      if(!in.is_open())
{
   cout << "Invalid filename!" << endl;
}
      else
{
   break;
}
    }

readPlayerData(playerArray, numPlayers, in);
bubbleSort(playerArray, numPlayers);
outputResults(playerArray, numPlayers);

in.close();

cout << endl;

return 0;
}

void readPlayerData(playerType playerArray[], int& numPlayers,ifstream& in)
{
string line;
while (getline(in, line))
    {
      stringstream ss(line);
      string n;
      int m;
   
      ss >> n;
     
      if (!n.empty() )
{
   n[0] = toupper(n[0]);
   for(size_t i = 1; i < n.length(); ++i)
     n[i] = tolower(n[i]);
}

      numPlayers++;
      }
}

void outputResults(playerType playerArray[], int numPlayers)
{
cout << left << setw(10) << fixed << "NAME" << "\t" << right << setw(7) << fixed << "UNIFORM#" << "\t" << right << setw(3) << fixed << "AVEPPG" << endl;
for (int i = 0; i < numPlayers; i++)
    {
cout << playerArray[i].name << fixed;
cout << right << setw(5) << playerArray[i].uniformNum;
cout << setprecision(2) << fixed;
cout << right << setw(5) << playerArray[i].averagePoints << endl;
    }
return;
}

void bubbleSort(playerType playerArray[], int numPlayers)
{
playerType temp;
for (int i = 0; i < numPlayers - 1; i++)
    for (int j = 0; j < numPlayers - (i+1); j++)
      if (playerArray[j].averagePoints > playerArray[j+1].averagePoints)
{
   temp = playerArray[j];
   playerArray[j] = playerArray[j+1];
   playerArray[j+1] = temp;
}
}
