Unsure How to Declare Winner in Array After Sorting

[fsm0019]

Hello, thank you in advance for any help. I have a code that asks for the scores between two teams stored inside a double array. After I find the scores I need to find the difference between each score, and sum the differences per team. Whichever team has the largest sum is the winner, and I have a code that works, but I do not know how to declare the winner of the game.

#include <iostream>
using namespace std;

const int SIZE = 4;
void det_win(int diff[][4], int SIZE);
int main()
{
	int scores[4][4], diff[4][4];
	int i , j;
	for (i=0; i < 4; i++)
	{
		for (j=0; j < 4; j++)
		{
			if (i != j)
			{
				cout << "Please enter the score of team " << i+1 << " versus team " << j+1 << "." << endl;
				cin >> scores[i][j];
			}
		}
	}
	for (i=0; i<4; i++)
	{
		for (j=0; j<4; j++)
		{
			diff[i][j] = scores[i][j] - scores[j][i];
		}
	}
	det_win(diff, SIZE);
return 0;
}

void det_win(int diff[][4], int SIZE)
{
	int i, j = 0, k;
	int sum_row[4] = {0,0,0,0};
		for(j=0; j<4; j++)
		{
			i=0;
			sum_row[i] += diff[i][j];
		}
		for(j=0; j<4; j++)
		{
			i=1;
			sum_row[i] += diff[i][j];
		}	
		for(j=0; j<4; j++)
		{
			i=2;
			sum_row[i] += diff[i][j];
		}
		for(j=0; j<4; j++)
		{
			i=3;
			sum_row[i] += diff[i][j];
		}

	int temp;
	for(i=3; i>0; i--)
	{
		for(k=0; k<i; k++)
		{
			if(sum_row[k] < sum_row[k+1])
			{
				temp=sum_row[k+1];
				sum_row[k+1]=sum_row[k];
				sum_row[k]=temp;
			}
		}		
	}
	cout << "Team " << ___ << " is the winner! They won with a score of " << temp << "." << endl;
return;
}

I ended up using a different sorting mechanism to find the answer, and this is the code I ended up going with that worked if anyone comes across this lost!

#include <iostream>
using namespace std;

const int SIZE = 4;
void det_win(int diff[][4], int SIZE);
int main()
{
	int scores[4][4], diff[4][4];
	int i , j;
	for (i=0; i < 4; i++)
	{
		for (j=0; j < 4; j++)
		{
			if (i != j)
			{
				cout << "Please enter the score of team " << i+1 << " versus team " << j+1 << "." << endl;
				cin >> scores[i][j];
			}
		}
	}
	for (i=0; i<4; i++)
	{
		for (j=0; j<4; j++)
		{
			diff[i][j] = scores[i][j] - scores[j][i];
		}
	}
	det_win(diff, SIZE);
return 0;
}

void det_win(int diff[][4], int SIZE)
{
	int i, j=0, k;
	int sum_row[4] = {0,0,0,0};
		for(j=0; j<4; j++)
		{
			i=0;
			sum_row[i] += diff[i][j];
		}
		for(j=0; j<4; j++)
		{
			i=1;
			sum_row[i] += diff[i][j];
		}	
		for(j=0; j<4; j++)
		{
			i=2;
			sum_row[i] += diff[i][j];
		}
		for(j=0; j<4; j++)
		{
			i=3;
			sum_row[i] += diff[i][j];
		}

	int max = 0;
	max=sum_row[0];
	int maxindex = 0;
	for (i=0; i<4; i++)
	{
		if(max<sum_row[i])
		{
			max=sum_row[i];
			maxindex=i;
		}
	}
	

	cout << "Team " << maxindex+1 << " is the winner! They won with a score of " << max << "." << endl;
return;
}
