Hello,

This question pertains to a programming problem that I have stumbled across in my C++ programming class.

The Assignment:
-----------------------------------------------------------------------------------
Number Analysis Program

Write a program that asks the user for a file name. Assume the file contains a series of numbers, each written on a separate line. The program should read the contents of the file into an array and then display the following data:

The lowest number in the array
The highest number in the array
The total of the numbers in the array
The average of the numbers in the array
-----------------------------------------------------------------------------------


This is what I have so far and I don't know where to go from here to make i give a total sum of the numbers in the file or an average. I can't even get it to open the file in question, x.x

	ifstream  inFile;
	string    filename = "";
	
	//Requests the name of the file the User wants to use.
	cout << "Please give me the name of the file." << endl;
	cin >> filename;

	//Opens the file the User specified.
	inFile.open(filename.c_str());

	while (index < ARRAY_SIZE && inFile >> numbers[index]);

	do

	cout << endl;

	if(index == 12)

		highestNumber = numbers[0];
	}
	if(lowestNumber > numbers[index])
		lowestNumber = numbers[index];
	if(highestNumber < numbers[index]);
		highestNumber = numbers[index];
		index++;

while(index < ARRAY_SIZE);

cout << "The lowest value in the document is:\n\n";
cout << "The highest value in the document is:\n\n";

int total = 0;
for(int index = 0; index < ARRAY_SIZE; index++)
	sum += total;



	inFile.close();

	} while(index == 12);


	return 0;

Your while loop syntax is incorrect. Check that first and see how much it helps.

I'm not sure I understand.. I added a '{' after the first while and removed the 'do', but when I run the program and enter the .txt file name it doesn't do anything at all.

You shouldn't have semicolons after you while() statement.

while(...);
{
//code
}

Is really equivalent to:

while(...) {
// nothing
}
{
//code
}

Oh, okay. That made it go to "Press any key to continue..." but it still didn't initiate the while loop or anything?
