Processing text files sequentially

[YellowHeart]

I am a beginner computer science student this summer and i have been having issues understanding what i am doing wrong. I wrote this to process the text in a file which i included in the resources file but I cannot seem to load my text file.

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>

using namespace std;

int main()

{
	ifstream infile;
	ofstream outfile;
	string name;
	double x = 0, highest = 0, lowest = 0, total = 0, average = 0;

	infile.open("data.txt");

		if (!infile)
		{
			cout << "Cannot open file, Terminating program." << endl;
			exit(1);
		}

	outfile.open("out.txt");

		while (infile)
		{
			total = 0, highest = 0, lowest = 0, average = 0;
			for (int i = 0; i < 7; i++)
			{
				infile >> x;
				total += x;
				if (i == 0 || highest < x)
					highest = x;
				if (i == 0 || lowest > x)
					lowest = x;
				cout << x << endl;

			}
			average = total / 7;

			cout << total << " \t is the total" << endl;
			cout << average << "\t is the average" << endl;
			cout << highest << " \t is the highest number" << endl;
			cout << lowest << "\t is the lowest number" << endl;
			system("pause");
		}

	infile.close();
	outfile.close();
	return 0;
}

data file is:

346	130	982	90	656	117	595
415	948	126	4	558	571	87
42	360	412	721	463	47	119
441	190	985	214	509	2	571
77	81	681	651	995	93	74
310	9	995	561	92	14	288
466	664	892	8	766	34	639
151	64	98	813	67	834	369

Your executable and the data file must be in the same directory.

You can use perror to display a more informative error msg if the file doesn't open.

if (!infile)
{
  perror("File error: ");
  cout << Terminating program." << endl;
  exit(1);
}
