filling spaces in a string.

I'm having an issue with a loop to fill in spaces of a string so it can display a table properly. I dont know why its not working but it should; Ive tried everything with this thing and no go. Basicall I need the string studentName to loop, and the names to all be equal when I do a setw. Any help is appreciated.

for (int x = 1; x <= 6 - nameSpaces; x++)
oStream << 'x';

Code:

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

using namespace std;

void CalculateAverage(int, int, int, int, int, int &);
char CalculateGrade(int);

int main()
{
    int average = 0;
	int classAverage = 0;
    int grade1, grade2, grade3, grade4, grade5;
	int class1 = 0;
	int class2 = 0;
	int class3 = 0;
	int class4 = 0;
	int class5 = 0;
	int students = 0;
	string studentName;
	int nameSpaces = studentName.length();

    ifstream iStream;
	ofstream oStream;

	cout << "Working..."<<endl;

	iStream.open("c:iStream.txt");
	oStream.open("c:averages.txt");

	oStream << "Name       Test1  Test2  Test3  Test4  Test5  Avg     Grade" << endl;
	oStream << "-----      -----  -----  -----  -----  -----  ---     -----" << endl;

    iStream>>studentName;

	while (iStream)
	{
	    iStream>>grade1;
		class1 += grade1;

	    iStream>>grade2;
		class2 += grade2;

		iStream>>grade3;
		class3 += grade3;

		iStream>>grade4;
		class4 += grade4;

		iStream>>grade5;
		class5 += grade5;

        students++;

		CalculateAverage(grade1, grade2, grade3, grade4, grade5, average);

		classAverage += average;



		oStream<<studentName;

		for (int x = 1; x <= 6 - nameSpaces; x++)
		oStream << 'x';  //<-----Problem here
	
		oStream <<setw(8)<<grade1<<setw(8)<<grade2<<setw(8)<<grade3<<setw(8)<<grade4<<setw(8)<<grade5<<setw(8);
		oStream	<<average <<setw(8)<<CalculateGrade(average)<<endl;

        iStream.ignore(100, '\n');

		iStream>>studentName;

	}

    class1 = class1 / students;
	class2 = class2 / students;

	oStream<<"---------------------------"<<endl;
	oStream<<setw(2)<<"Class"<<setw(7)<<class1<<setw(8)<<class2<<setw(8)
            <<class3<<setw(8)<<class4<<setw(8)<<class5<<setw(8)<<classAverage
			<<setw(8)<<CalculateGrade(classAverage)<<endl;


	iStream.close();
	class3 = class3 / students;
	class4 = class4 / students;
	class5 = class5 / students;
	classAverage = classAverage / students;


	oStream.close();
	cout<<"File ready."<<endl;
    return 0;
}

void CalculateAverage(int grade1, int grade2, int grade3, int grade4,
                        int grade5, int &average)
{
    average = (grade1 + grade2 + grade3 + grade4 + grade5) / 5;
	return;
}

char CalculateGrade(int score)
{
    if (score >= 90)
	    return 'A';

	else if (score >= 80)
	    return 'B';

	else if (score >= 70)
	    return 'C';

	else if (score >= 60)
	    return 'D';

	else
	    return 'F';
}

why x's?

it seems to me like you just want to do

cout << name << setw(strlen(studentName) - columnWidth) << ....... ;

.....any way....namespaces has the value of zero.... i haven't looked real hard at your code, but just from skimming it i can tell you that that is your biggest problem...

by the way... nameSpaces isn't a very good variable name because "namespace" is a c++ keyword

edit: double post

Code:

int nameSpaces = studentName.length();

At the time you set nameSpaces, studentName is empty, so nameSpaces is always 0. Your for loop will then output 6 'x's every time. I'm not sure exactly what you are trying to do, but maybe you should add the nameSpaces code just after you get the name before and in the loop.

Code:

iStream>>studentName;
nameSpaces = studentName.length();
