<iomanip> format with setw(#)

[PiggiesGoSqueal]

I'm having trouble with getting the formatting to work with setw(). I've spent 2 hours on this.. and I thought it would be a simple task..

I'm just trying to get my current setup to have the correct format then I'll work on the rest of it.

Help would be greatly appreciated. Thank you!

Please note:
I've already checked the cplusplus.com part on <iomanip> and setw() but there weren't many examples. Then I checked this: https://en.cppreference.com/w/cpp/io/manip/setw but it doesn't seem to be working as it shows or as I'd expect..

Code Snippet:

		if (!fout.fail()) { // if the output file has been opened successfully:
			// Writes to output file
			// Line 1:
			fout << setfill('=') << setw(78) << '\n';
			// Line 2:
			fout << "fname" << setfill(' ') << setw(15) << "lname"
				<< setw(18) << "test1" << setw(8) << "test2"
				<< setw(8) << "test3" << setw(8) << "test4"
				<< setw(10) << "avg." << setw(8) << "grade"
				<< '\n';
			// Line 3:
			fout << setfill('=') << setw(78) << '\n';
			// Lines with Data:

			for (int i = 0; i < arrSize - 1; i++) {
				fout << setfill(' ');
				// Each Line with Data: (THE CODE BELOW IS THE PROBLEM CODE)
				fout << right << arr[i].fName <<
					setw(21) << arr[i].lName << '\n';

			}
			// Closing output file
			fout.close();
		}

fout << left  << setw(21) << a[i].fName         << ' '
              << setw(21) << a[i].lName         << ' '
     << right << setw( 8) << a[i].someNumber    << ' '
              << setw( 8) << a[i].anotherNumber << '\n';

Note that it's important to output an actual space between the values. Otherwise if a value fills its field it will run-on with the next one.

For the floating point value, you're also going to want to do a

cout << fixed << setprecision(2);

It only needs to be done once.
