Using three arrays: a one-dimensional array to store the students’ names, a (parallel) two-dimensional array to store the test scores, and a parallel one-dimensional array to store grades. your program must contain at least the following functions: a function called getdata to read and store data into two arrays, a function called average that is used to calculate the average test score and grade, and a function called printresults to output the results. the student names should be to the left with a width of 10 columns. the test scores should be to the right with a width of 5 columns. have your program also output the class average on a line after the output.
3 serperate arrays should be used
and it should read from a file
ive used some void functions two dimensional arrays to read numbers from a text file but im getting a lot of errors i know setw needs to be used also

This C++ program considers scores as follows

A>=90

B>=80

C>=70  

D>=60

F<60

You must have a text file for input data

Here is the program as per the question

#include<iostream>

#include<fstream>

#include<string>

#include<stdlib.h>

using namespace std;

//Definition

class student

  {

  private:

  string names[80];

  int testscores[80][50];

  char grades[80];

  int count;

  public:

      void GetData();

      void Average();

      void PrintResult();

  };

void student::GetData()

  {

  ifstream in;

  in.open("student1.txt",ios::in);

  if(in.fail())   //test if the file exist

      {

          cout<<"Unable to open the file";

          exit(0);

      }

  count=0;

  while(!in.eof())  

      {

      in>>names[count];   //read name

      for(int i=0;i<5;i++)   // assume 5there are 5 test scores

          {

              in>>testscores[count][i];   //read scores .

          }

      count++;

      }

  count--;

  }

void student::Average()

  {

  float sum,avg;

  for(int i=0;i<count;i++)

      {

      sum=0.00;

      for(int j=0;j<5;j++)

          {

          sum=sum+testscores[i][j];

          }

      avg=sum/5;

      if(avg>=90.00)

          grades[i]='A';

      else if(avg>=80)

          grades[i]='B';

      else if(avg>=70)

          grades[i]='C';

      else if(avg>=60)

          grades[i]='D';

      else

          grades[i]='F';

      }

  }

void student::PrintResult()

  {

  for(int i=0;i<count;i++)

      {

      cout.setf(ios::left,ios::adjustfield);

      cout.width(10);

      cout<<endl<<names[i];

      cout.setf(ios::right,ios::adjustfield);

      for(int j=0;j<5;j++)

          {

          cout.width(5);

          cout<<testscores[i][j];

          }

      cout.width(5);

      cout<<grades[i];

      }

  }

  int main()

  {

      student obj;

      obj.GetData();

      obj.Average();

      obj.PrintResult();

      return 0;

  }
