Formatting output text file

[Sheepman]

My quest, to put 100 random numbers in ten rows of ten. Then output the same to the screen and a file. My screen output is working,yeah! Text file, not so much. The data is getting there but not formated. If word wrap is off it's a single row. If word wraps on, well ... it wraps. I've considered sizing the notebook window to wrap at the tenth character but I don't think the TA working on his Phd will buy it. Help please! My code for this portion is below:

void tenByTen(int firstArray[])
{
char yourFileName [80];
int d1, d2;
//Prompt user for file name to store array
cout << "Enter name of file to store your randomly generated numbers: " << endl;
cin >> yourFileName;
ofstream outfile (yourFileName, ios::out);//create and open file
if (!yourFileName)//errorcheck
{
    cout << "Error opening your file " << endl;
}//close error check
//fomat array output to 10 x 10
 
for (d1 = 0; d1 <= 9; d1++)
{
    for (d2 = 0; d2 <= 9; d2++)
    {
     cout << setw(5) << firstArray[(d1 * 10) + d2];//write to screen
     outfile << setw(4) << firstArray[(d1 * 10) + d2];//write to file     
    }//close nested for
    cout << endl;
}//close for
outfile.close();
}//close tenBy

Look how you are sending a message to the screen to tell it to start a new line after every 10 numbers:

cout << endl;

It works, right?
All you need to do is send a similar message to your file at the same time, telling it to start a new line as well.

look all u need to so is to write
outfile<<endl;
after cout<<endl;


given below
for (d1 = 0; d1 <= 9; d1++)
{
for (d2 = 0; d2 <= 9; d2++)
{
cout << setw(5) << firstArray[(d1 * 10) + d2];//write to screen
outfile << setw(4) << firstArray[(d1 * 10) + d2];//write to file
}//close nested for
cout << endl;
outfile<<endl;
}//close for
outfile.close();
}//close tenBy

I spent 4 or 5 hours trying to figure this out. I kept using

cout<<endl;

instead of

outfile<<endl;

. I've only been doing this 4.5 weeks. It's the little things that really seem to kill me.

Don't I look silly!

My book doesn't say anything about this. I kept trying to use

cout<<endl;

in every combination imaginable. Inside the brackets, outside the brackets, commenting out the write to screen portion. I'm not to clear on how to debug yet. So I don't know how to use it to my advantage, to see at what point the program stops outputting my expected results.
