Question

Hello I need help fixing my C++ code. I need to display in the console the information saved in the file as well have the content saved in the file output in a fixed position like the screenshot. Thanks.

CODE

#include<iostream>
#include<fstream>
#include<iomanip>

using namespace std;

//main function
int main()
{
   //variable to store student id
   int id;
  
   //variables to store old gpa(ogpa), old course credits(occ), new course credits(ncc), current gpa(cur_gpa), cumulative gpa(cum_gpa)
   float ogpa, occ, ncc, cur_gpa, cum_gpa;
  
   //variables to store course credits
   float c1, c2, c3, c4;
  
   //variables to store grades
   float g1, g2, g3, g4;
  
   //variables to store old honor points and new honor points
   float ohp, nhp;
  
   //variables for input file name and output file name
   char in_file_name[100],out_file_name[100];
  
   //objects for read from file and write to file
   ifstream in_stream;
   ofstream out_stream;
  
   //prompt for input file name
   cout << "Enter the input file name: ";
   cin >> in_file_name;
  
   //prompt for output file name
   cout << "Enter the output file name: ";
   cin >> out_file_name;
  
   //opening input file
   in_stream.open(in_file_name);
  
   //reading student id, old gpa, old course credits
   in_stream >> id >> ogpa >> occ;
  
   //reading course credits
   in_stream >> c1 >> c2 >> c3 >> c4;
  
   //reading grades
   in_stream >> g1 >> g2 >> g3 >> g4;
  
   //calculating old honor points
   ohp = occ * ogpa;
  
   //calculating new honor points
   nhp = (c1 * g1) + (c2 * g2) + (c3 * g3) + (c4 * g4);
  
   //calculating new course credits
   ncc = c1 + c2 + c3 + c4;
  
   //calculating current gpa
   cur_gpa = nhp / ncc;
  
   //calculating cumulative gpa
   cum_gpa = (nhp + ohp) / (ncc + occ);
  
   //opening output file
   out_stream.open(out_file_name);
  
   //writing student id to file
   out_stream << "Student ID number:\t\t\t\t" << id << endl;
  
   //writing old course credits to file
   out_stream << "Previous semester's credit:\t\t" << occ << endl;
  
   //writing old gpa to file
   out_stream << "Previous semester's GPA:\t\t" << ogpa << endl;
  
   //writing current gpa to file
   out_stream << "GPA of current semester:\t\t" << fixed << setprecision(1) << cur_gpa << endl;
  
   //writing cumulative gpa to file
   out_stream << "Cumulative GPA:\t\t\t\t\t" << fixed << setprecision(1) << cum_gpa << endl;
  
   //writing total credits to file
   out_stream << "Total credits completed:\t\t" << fixed << setprecision(0) << (occ + ncc) << endl;
  
   //closing input file
   in_stream.close();
  
   //closing output file
   out_stream.close();
}

Screenshot:

Write a program to calculate the current semester's grade point average and the cumulative grade point average of a student. The program should use an input data file to: 1. read the student's six-digit identification number (id ), his/her old grade point average (ogpa), and the old number of course credits (oce) 2. read the course credits (cl, c2, c3, c4) and grades (gl, g2, 93, 94) for each of four courses 3. compute: old number of honor points = ohp = occ xogpa new number of honor points = nhp =cl x gl + c2 x g2 + c3 x g3 + c4 x 34 total number of new course credits = nec =cl + c2 + c3 + c4 current GPA = cur_gpa=nhp/ncc cumulative GPA = cum_gpa=(nhp + ohp)/(nce + oce) The input data file should be created such that id, ogpa, and occ are placed on the first line, cl, c2, c3, and c4 are listed on the second line, and gl, g2, g3, and g4 are listed on the third line; as an example, the input file could contain the following data: 213141 3.2 5 24 4 2 All outputs should be written to an output file which has a format exactly like the following. Student ID number: 213141 Previous semesters' credit: Previous semesters' GPA: GPA of current semester: Cumulative GPA: Total credits completed:

Dear student copy and past the below code and run you will get the output in correct formate

#include<iostream>
#include<fstream>
#include<iomanip>

using namespace std;

//main function
int main()
{
//variable to store student id
int id;
  
//variables to store old gpa(ogpa), old course credits(occ), new course credits(ncc), current gpa(cur_gpa), cumulative gpa(cum_gpa)
float ogpa, occ, ncc, cur_gpa, cum_gpa;
  
//variables to store course credits
float c1, c2, c3, c4;
  
//variables to store grades
float g1, g2, g3, g4;
  
//variables to store old honor points and new honor points
float ohp, nhp;
  
//variables for input file name and output file name
char in_file_name[100],out_file_name[100];
  
//objects for read from file and write to file
ifstream in_stream;
ofstream out_stream;
  
//prompt for input file name
cout << "Enter the input file name: ";
cin >> in_file_name;
  
//prompt for output file name
cout << "Enter the output file name: ";
cin >> out_file_name;
  
//opening input file
in_stream.open(in_file_name);
  
//reading student id, old gpa, old course credits
in_stream >> id >> ogpa >> occ;
  
//reading course credits
in_stream >> c1 >> c2 >> c3 >> c4;
  
//reading grades
in_stream >> g1 >> g2 >> g3 >> g4;
  
//calculating old honor points
ohp = occ * ogpa;
  
//calculating new honor points
nhp = (c1 * g1) + (c2 * g2) + (c3 * g3) + (c4 * g4);
  
//calculating new course credits
ncc = c1 + c2 + c3 + c4;
  
//calculating current gpa
cur_gpa = nhp / ncc;
  
//calculating cumulative gpa
cum_gpa = (nhp + ohp) / (ncc + occ);
  
//opening output file
out_stream.open(out_file_name);
  
//writing student id to file
out_stream << "Student ID number: " << id << endl;
  
//writing old course credits to file
out_stream << "Previous semester's credit: " << occ << endl;
  
//writing old gpa to file
out_stream << "Previous semester's GPA: " << ogpa << endl;
  
//writing current gpa to file
out_stream << "GPA of current semester: " << fixed << setprecision(1) << cur_gpa << endl;
  
//writing cumulative gpa to file
out_stream << "Cumulative GPA: " << fixed << setprecision(1) << cum_gpa << endl;
  
//writing total credits to file
out_stream << "Total credits completed: " << fixed << setprecision(0) << (occ + ncc) << endl;
  
//closing input file
in_stream.close();
  
//closing output file
out_stream.close();
}

output:
