Trouble with fstream

[redjazmin]

So I was going through my textbook and doing some of the fstream examples. I got through some of them except the ones where I am trying to read from a file. In my previous program I entered the following numbers 50, 40, 30, 20 to be read in this program. When I run this program I get " -858993460 -858993460 -858993460 -858993460. Their sum is 858993456." What exactly am I doing wrong?

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

int main()
{
	ifstream inFile;
	int value1, value2, value3, value4, sum;

	//Open the file.
	inFile.open("Numbers.txt");

	//Read the four numbers from the file.

	inFile >> value1;
	inFile >> value2;
	inFile >> value3;
	inFile >> value4;

	//Close the file.
	inFile.close();

	//Calculate the sum of the numbers.

	sum = value1 + value2 + value3 + value4;

	//Display the four numbers.
	cout << "Here are the numbers: \n"
		<< value1 << " " << value2
		<< " " << value3 << " " << value4
                << endl;

	// Display the sum of the numbers.
	cout << "Their sum is: " << sum << endl;
	cin.get();
	return 0;
}

You should always make sure to check that the file was found and opened correctly. Everything else looks ok.

if(!inFile)
    cout << "There was a problem with this file " << endl;

So I added the code you wrote and it did tell me there was a problem with the file. I copied the txt file into same file my project was in and it fixed it. I rechecked my book for an example.

inputFile.open("C:\\data\\inventory.txt")

If I add that code I wouldn't have to make multiple copies of the txt file.

Thanks.

As a rule of thumb, you probably should never assume something was successful unless you can't afford to check for errors (which is almost never the case).
