Create a program to read in 10 student grades data from file. The file contains student ID and scores for three exams.

Each row should contain 4 columns: here is my example below,

Student ID,      Exam1 grade,             exam2 grade,             exam 3 grade

14524              89                                78                                            95

25437              96                                88                                            95

The program reads the grades for students, calculates average of three exams for each student, and puts out to another file (called Summarygrades.txt) Student ID average and letter grade: example below,

Student Id       Average grade                        Letter grade

14524              87.3                                         B

...ETC....         

Here's what I got so far:

#include
#include
#include
using namespace std;
int main()
{
   double studentgrades, x;
   ifstream infile;
   char studentgrades[10];

   //prompt user for file to be opened and declare what you're reading from
   cout << "Please enter the student file" << endl;
   cin >> studentgrades;
   cout << "The file you entered is: " << studentgrades << endl;

   //Prompt for error
   if (!infile)
   {
       cerr << " Error opening file.\n ";
       exit(1);
   }
  
   //file opens
   for (int i = 0; i < 10; i++);
   {

   }

}
