Structure arrays?

Question

C++ / C#

Task:

Known data on the cost of each of the 15 car models and their type (passenger or truck). Find the average cost of cars.

Here is what I have written so far, I don’t know how to calculate further

#include <iostream>
#include <string.h>

using namespace std;

struct Auto
{
  char marka[15];
  int tup, price;
};

void Auto_desh(struct Auto *m, int n);

int main()
{
  const int n=2;
  Auto M[n];

  string marka [15]{
  "BMW", "Audi"};
  
  string tup [15]{
  "Vaz", "Leh"};
  
  string price [15]{
  "1000", "500"};
  
  cout<<"E taki auto\t";
  for (int i = 0; i < n; i++) {
  cout<<marka[i]<<"\t"<<tup[i]<<"\t"<<price[i]<<endl;
  }
return 0;
}

using namespace std;

  }
  string ToString() {

    std::stringstream result;
    result << "Model: " << this->Model <<
      ", Price: " << this->Price <<
      ", Type: " << this->TypeAuto;
    return result.str();
  }
};

  auto cargo = AveragePriceByType(cars, Car::Type::Cargo);
  auto passenger = AveragePriceByType(cars, Car::Type::Passenger);
  
  cout << "Вывод грузовых автомобилей: " << endl;

    return 0;
