Explanation / Answer

Complete Program:

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
using namespace std;

struct Car
{
int id;
int modelYear;
string model;
string trim;
string color;
int engine;
};

int main()
{
const int MAX = 10;
Car Honda[MAX];
int count = 0;
int id;

ifstream infile;
infile.open("inventory.txt");

if(!infile)
{
  cout << "Input file cannot be opened!" << endl;
  system("pause"); // for Visual Studio
  exit(EXIT_FAILURE);
}

infile >> id;
while(infile && count < MAX)
{
  Honda[count].id = id;
  infile >> Honda[count].modelYear;
  infile >> Honda[count].model;
  infile >> Honda[count].trim;
  infile >> Honda[count].color;
  infile >> Honda[count].engine;
  count++;

  infile >> id;
}
infile.close();

ofstream outfile("accord6.txt");

int n = 0;
outfile << "Six Cylinder Accords in Stock" << endl << endl;
outfile << left << setw(10) << "ID" << setw(10) << "Year" << setw(12) << "Model" << setw(15) << "Trim" << setw(10) << "Color" << setw(12) << "Engine(4/6)" << endl;
for(int i = 0; i < count; i++)
{
  if(Honda[i].engine == 6)
  {
   outfile << left << setw(10) << Honda[i].id << setw(10) << Honda[i].modelYear << setw(12) << Honda[i].model << setw(15) << Honda[i].trim << setw(10) << Honda[i].color << setw(12) << Honda[i].engine << endl;
   n++;
  }
}
outfile << " Total number of 6 cylinder Accords in stock = " << n << endl;
outfile.close();

system("pause"); // for Visual Studio
return 0;
}

Input file: inventory.txt

Output file: accord6.txt
