Need to make a program that read student names and marks from a file.

[student2]

The Task

The problem is to read student names and marks from a file, grade them and display the details (names and grades) on screen together with the highest score.

Method
Setup a class to store a student. The data is to include a first name, last name, tests core(whole number) and a grade (A..F). The class should include functions to read a student name and score from a file, to determine the grade from the score and to display that student’s details on screen. You may require other functions, that is for you to decide.

The main program should contain an array of student objects which are used in conjunction with the file to load all students’ results. Your program should handle up to 20 student’s results.

I cant attach the file "students.txt" so I have to post under this.

In this exercise it is expected you will require at least two non-class functions to calculate the highest score and to display all the results. The grades are to be awarded as follows:90 and over A, 80-89 B, 70-79 C, 60-69 D, less than 60 F.

so far i have done this much


#include <iomanip>
#include <fstream>
#include <iostream>
using namespace std;

class student;
public
string FristName;
string LastName;
float testscore;
string grade;



int main()
{


cout<< Student’s Details !!!! <<endl;


system("pause");
return 0;
}

What you'll need:

//What varibles will you need?
//An int to hold test scores
//A string to hold the names of each student
//EX:
//int Grade
//std::string Name[2] - For first and last name


void student::SetArr(/*What will you need to put in here?*/)
{
    //ifstream Obj("File.txt")
    for(int i = 0;i<ArSize;i++) //ArSize is a constant you defined in the student class
        //Read file into array
        
}

void student::CalculateScores(/*Parameters here*/)
{
    //if(code here)
}

void student::DisplayResults(/*Paramters*/)
{
    //DISPLAY
}

This is a hollow shell of how it might be done. Im going to go ahead and code it then come back and fix this.

thank you Ill try n let u know. I need to do this program in C++

[student2]

I have re edit it plz have look n let me knw where i got wrong


#include <iomanip>

#include <iostream>
using namespace std;

class student;
{

private:
string firstName,lastName;
float testScore;
char grade;

public:
void SetUpStudent(string,string,float);
void CalculateGrade();
void DisplayResults;
float returnScore();


}


void student::SetUpStudent(string fname,string lname,float score)
{
firstName=fname;
lastName=lname;
testScore=score;
calculateGrade();
}

void student::CalculateGrade()
{
if(testScore >=90)
{
grade='A';
}else{
if(testScore >=80 & testScore <90)
{
grade='B';
}else{
if(testScore >=70 & testScore <80)
{
grade='C';
}else{
if(testScore >=60 & testScore <70)
{
grade='D';
}else{
grade='F';
}
}

void student::DisplayResults()
{
cout << "Student Name: " << firstname <<" " <<lastname <<endl <<"Test Score: " << testScore <<endl <<"Grade: " << grade <<endl;
}

float student::returnScore();
{
return testScore;
}
