Converting program to use arrays

[forbesthebrit]

Hi,
I have a program that reads data from an input file, uses 3 nested loops, and writes the data to an output file. It stores 3 students personal info, and 5 grades for 3 different courses and calculates a final grade along with a warning or congratulations quote. It works fine but this current project wants me to read all the input data and store it into separate arrays, compute the final grade, store that in one of the arrays, and then write all of the data in the arrays to an output file in the same formatting as before. I am having major issues wrapping my head around this.

This is the part of my old program with the loops:

    //First loop for reading and printing the Student Information
	for (int a = 1; a <= studentNumber; a++)
    {
        //Reading Student information from the input file
        getline(fin,name);
        if (name.length() <= 1)                                         //Validating the name length
        {
            cout << "Student Name is incorrect.\n";
            continue;
        }
        fin >> age;
        if (age < 1 || age > 100)                                       //Validating the age
        {
            cout << "Student age is incorrect.\n";
            break;
        }
        fin.ignore ();
        getline(fin,address);
        if (address.length() <= 1)                                      //Validating the address length
        {
            cout << "Student address is incorrect.\n";
            continue;
        }
        fin >> years;
        if (years < 1 || years > 100)                                   //Validating the years
        {
            cout << "Student years is incorrect.\n";
            break;
        }
        fin.ignore ();
        getline(fin,tel);
        if (tel.length() <= 1)                                          //Validating the telephone length
        {
            cout << "Student telephone number is incorrect.\n";
            continue;
        }
        getline(fin,social);
        if (social.length() <= 1)                                       //Validating the social security number length
        {
            cout << "Student social security number is incorrect.\n";
            continue;
        }

This is what i have so far with my new loops using arrays:

for (int a = 0; a < StudentNum; a++)
    {
        for (int b = 0; b < NonNumData; b++)
        {
            getline(fin,studentStringData[a][b]);
            if (studentStringData[a][b].length() <= 1)
            {
                cout << "Student Data is incorrect.\n";
                continue;
            }
        }
        for (int c = 0; c < NumData; c++)
        {
            fin >> studentNumData[a][c];
            if (studentNumData[a][c] < 1 || studentNumData[a][c] > 100)
            {
                cout << "Student Data is incorrect.\n";
                break;
            }
        }
        for (int d = 0; d < NumCourses; d++)
        {
            for (int e = 0; e < 5; e++)
            studentGrades [a][d][5] = (studentGrades [a][d][0] * test1Percentage) + (studentGrades [a][d][1] * test23Percentage) +
                                      (studentGrades [a][d][2] * test23Percentage) + (studentGrades [a][d][3] * test4Percentage) + (studentGrades [a][d][4] * examPercentage);
            {
                fin >> studentGrades [a][d][e];
                fin.ignore();
                if (studentGrades [a][d][e] < 1 || studentGrades [a][d][e] > 100)
                {
                    cout << "Student Data is incorrect.\n";
                    break;
                }
            }

        }

I have 4 arrays, since they are all different types of data:

string studentStringData [StudentNum][NonNumData];
    int studentNumData [StudentNum][NumData];
    double studentGrades [StudentNum][NumCourses][NumGrades];
    char studentLetterGrades [StudentNum][NumCourses];

I just dont know how to calculate the final grade in the loop since the percentages for the different tests are all different and i need the final grade to be the 6th element of the array studentGrades

Grade Assessment Item Percentage of
Final Grade
Exam #1 (0.0 - 100.0) 10%
Exam #2 (0.0 - 100.0) 15%
Exam #3 (0.0 - 100.0) 15%
Exam #4 (0.0 - 100.0) 20%
Exam #5 (0.0 - 100.0) 40%

[forbesthebrit]

I feel that i might have to put my outputs inside the loops like i did before, but i am not sure how to do that since they need different headings...

[shadowCODE]

this current project wants me to read all the input data and store it into separate arrays

. Also from your past post,

length,age,address,years,telephone,security number, test1 to test4,exam

Does this mean that there are several records of these data in the file?
If yes, then you can use separate arrays for each field. If you dont know how many records are in the file, think of vector.

From you last post,

string studentStringData [StudentNum][NonNumData];
int studentNumData [StudentNum][NumData];
double studentGrades [StudentNum][NumCourses][NumGrades];
char studentLetterGrades [StudentNum][NumCourses];

//if an array is declared "type x", then it can only hold data of "type x".
//you have the same data, "stduentNum" in "string", "int","double", and "char" arrays.
//as well as others.
//You do not need multidimentionnal arrays here.

Hi shadowCODE, I guess i haven't been super specific, this thing is kicking my butt.
But the prof wants us to use multidimensional arrays. (some 2d, and a 3d) and i have one input file, with data for 3 students with their name, address, id number, telephone number, social, age, and years attended, and then 3 courses with 5 test grades, that looks like this:

The names you see in the [] when i declare the arrays are just named constants that hold a number ( for example, [StudentNum] is the same as [3] since i declared that StudentNum = 3 earlier on).

he wants the output file to look something like this:

Currently, i have gotten my loops this far:

	for (int a = 0; a < StudentNum; a++)
    {
        for (int b = 0; b < NonNumData; b++)
        {
            getline(fin,studentStringData[a][b]);
            if (studentStringData[a][b].length() <= 1)
            {
                cout << "Student Data is incorrect.\n";
                continue;
            }
            fout << studentStringData[a][b] << endl;
        }
        for (int c = 0; c < NumData; c++)
        {
            fin >> studentNumData[a][c];
            if (studentNumData[a][c] < 1 || studentNumData[a][c] > 100)
            {
                cout << "Student Data is incorrect.\n";
                break;
            }
            fout << studentNumData[a][c] << endl;
        }
        for (int d = 0; d < NumCourses; d++)
        {
            for (int e = 0; e < 5; e++)
            {
                fin >> studentGrades[a][d][e];
                fin.ignore();
                if (studentGrades[a][d][e] < 1 || studentGrades[a][d][e] > 100)
                {
                    cout << "Student Data is incorrect.\n";
                    break;
                }
                fout << studentGrades[a][d][e] << endl;
            }
            studentGrades[a][d][5] = (studentGrades [a][d][0] * test1Percentage) + (studentGrades [a][d][1] * test23Percentage) +
                                      (studentGrades [a][d][2] * test23Percentage) + (studentGrades [a][d][3] * test4Percentage) + (studentGrades [a][d][4] * examPercentage);
            fout << studentGrades[a][d][5] << endl;
        }

    }

and my output looks like this:

[forbesthebrit]

So I am getting all the right data in my arrays, and it is calculating the grade correctly, but i dont know how to output it correctly since i cannot assign the array data to separate variables like i did in the previous project.

[forbesthebrit]

So i am getting closer. I currently have the following and it output everything in the correct format except for the studentStringData, and the studentNumData. I put the courses into their own array since i could loop the course number output, and i looped the exam output, numerical grade output, and letter grade output.

The issue now is i dont know how to loop all of the string data and the num data inot the output since they all need different "headings"

for (int a = 0; a < StudentNum; a++)
    {
        for (int b = 0; b < NonNumData; b++)
        {
            getline(fin,studentStringData[a][b]);
            if (studentStringData[a][b].length() <= 1)
            {
                cout << "Student Data is incorrect.\n";
                continue;
            }
            fout << studentStringData[a][b] << endl;
        }
        for (int c = 0; c < NumData; c++)
        {
            fin >> studentNumData[a][c];
            fin.ignore();
            if (studentNumData[a][c] < 1 || studentNumData[a][c] > 100)
            {
                cout << "Student Data is incorrect.\n";
                break;
            }
            fout << studentNumData[a][c] << endl;
        }
        for (int d = 0; d < NumCourses; d++)
        {

Where the first 6 lines of data (which changes for each student) is in the string studentStringData array, and the Age, and Years attended are in the int studentNumData array

Well, i just decided that it wasn't possible and did it this way to get the correct output:

        for (int b = 0; b < NonNumData; b++)

            if (studentStringData[a][b].length() <= 1)
            {
                cout << "Student Data is incorrect.\n";
