C++ Array display winner's name - c++

Question

I have to calculate the total of scores the participants received from the judges. And the one who gets the highest score will be the winner. I have to display the name of the winner but it displays the wrong winner. how do I solve this?
int main(){
int scores[5][2], i, j; int sum =0;
string name [5];
for(int i=0;i<5;i++)
{
cout << "Enter participant's name: \n";
cin >> name[i];
cout<<"Enter scores for " << name[i] <<endl;
for(j=0;j<2;j++)
{
cin >> scores[i][j];
}
}
for(int i=0; i<5; i++)
{
sum = 0;
for(j=0; j<2; j++)
{
sum += scores[i][j];
}
cout<<"Total scores of " << name[i] << " " <<" is "<<sum<<endl;
}
int max, min, count;
int index[5];
max = min, count=0;
index[5]={0};
for(int i=0; i<5; i++)
{
for(j=0; j<2; j++)
{
if (scores[i][j]>max)
{
max=scores[i][j];
}
}
for(int i=0; i<5; i++)
{
if(scores[i][j]==max)
{
index[count]=scores[i][j];
count++;
}
}
if (count==1)
cout<<"The winner is " << index[count-1] << name[i] << endl;
}
return 0;
}

You could use a running maxima algorithm without having to store all entries.
int main()
{
std::string name;
int max_score = -1;
std::string owner_max_score;
cout << "Enter participant's name: \n";
while (std::getline(cin, name))
{
int score1, score2;
cout<<"Enter 2 scores for " << name <<endl;
cin >> score1 >> score2;
if (score1 > max_score)
{
max_score = score1;
owner_max_score = name;
}
if (score2 > max_score)
{
max_score = score2;
owner_max_score = name;
}
cout << "\nEnter participant's name: \n";
}
cout << owner_max_score << " has highest score of " << max_score << endl;
return 0;
}
To stop the loop, terminate the input. Some platforms use Ctrl-D, some use Ctrl-Z or Ctrl-C.

You could also use a std::vector of structs:
struct Student
{
std::string name;
int score1;
int score2;
void console_input()
{
std::cout << "\n"
<< "Enter student's name:\n";
std::getline(std::cout, name);
std::cout << "\n"
<< "Enter 2 scores for "
<< name
<< "\n";
std::cin >> score1 >> score2;
}
int max_score() const
{
return std::max(score1, score2);
}
};
int main()
{
Student s;
std::vector<Student> student_scores;
std::cout << "Enter quantity of students: ";
std::cint >> student_quantity;
for (int i = 0; i < student_quantity; ++i)
{
s.console_input();
student_scores.push_back(s);
}
std::string owner_max_score = student_scores[0].name;
std::int highest_score = student_scores[0].max_score();
for (int i = 1; i < student_quantity; ++i)
{
const int student_max_score = student_scores[i].max_score();
if (student_max_score > highest_score)
{
highest_score = student_max_score;
owner_max_score = student_scores[i].name;
}
}
std::cout << "\n\n"
<< owner_max_score
<< " has highest score: "
<< highest_score
<< "\n";
return 0;
}
