Answer 1

Please let me know if anything is required. I am happy to help you.

Please share me the grading ranges to give the grades for the each subject.

Code:

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

int main()
{
  
ofstream outfile;
outfile.open("file1.txt"); //to store the contents of student details in file1
  
ofstream outfile1;
outfile1.open("file2.txt"); //file listing all students and their average marks arranged in descending order

  
int number;
cout<<"Please enter how many students data you want to enter : "; //taking total number of students
cin>>number;
int grades[number]; //array to store the average marks
string names[number]; //array to store the names
  
for(int i=0;i<number;i++)
{
string student_name;
int student_number;
cout<<"Please enter student name and student number : "; //taking student name and student number from the user
cin>>student_name>>student_number;
names[i] = student_name;
  
//taking the marks for the each subject
int Set,Ma,Sci,Eng,Soc;
cout<<"Please Enter student marks for Setswana, Maths, Science, English, and Social Studies : ";
cin>>Set>>Ma>>Sci>>Eng>>Soc;
  
string Comments;
cout<<"Please enter any comments: ";
  
cin>>Comments; //taking Comments from the user
  
//writing the student and their marks details in file1
outfile<<"Student Name: "<<student_name<<" Student Number: "<<student_number<<" Course Name Marks % Letter Grade Setswana "<<Set<<" - Maths "<<Ma<< "B Science "<<Sci<<" English "<<Eng<<" - Social Studies "<<Soc<<" Average: "<<(Set+Ma+Sci+Eng+Soc)/5<<" Comments: "<<Comments<<"\n";
  
grades[i]=(Set+Ma+Sci+Eng+Soc)/5; //calculating the average marks

}
  
  
//sorting the names and the average marks according to the average marks
for (int i = 0; i < number-1; i++)   
{
for (int j = 0; j < number-i-1; j++)
{
if (grades[j] > grades[j+1])
{
int temp = grades[j];
grades[j] = grades[j+1];
grades[j+1]= temp;
  
string temp1 = names[j];
names[j] = names[j+1];
names[j+1] = temp1;
  
}
}
}
  
  
for (int j = number-1; j >= 0; j--)
{

outfile1<<names[j]<<" "<<grades[j]<<" "; //in descending order storing the names and average marks in second file
}
cout<<"\n";

return 0;
}
