Question

Write a complete program in C to get data from file name DATA.TXT one line at a time until there is no more data in that file. The following is one sample line in DATA.TXT ( have as many record as you wish in DATA.TXT) Name SSN quiz mid assignments participation final LISA 111-11-1111 100 100 100 100 100 Jack 222-22-2222 80 80 100 90 100 Note that the first line is no in DATA.txt. Your program should create a file name RESULT.txt that reports Name, SSN and a letter grade according to the following rules: Total= %15 quiz + %15 mid +%40assignments + %10 Participation+ %final If total >= 90 then A else if total>=80 then B…. You can print same output to screen as well as RESULT.txt. Thank you!

#include<iostream>
#include<string>
#include <fstream>
using namespace std;
main() {
   string name;
   string ssn;
   int quiz,mid,assn,part,final;  
   float total;
   char grade;

   char filename[100]="data.txt";
   ofstream outfile;
   outfile.open("result.txt");
   outfile <<"Name "<< "SSN "<< "Grade ";
   if (std::ifstream(filename))
       {
           ifstream infile(filename);
           std::getline(infile, name);
           while(infile >> name >> ssn >> quiz >> assn >> part >>final)
           {
                          
               total= .15*quiz + .15*mid + .4*assn+.1*part+ final;
               cout << final;
               if(total>=90) grade='A';
               else if(grade >=80 && grade <90) grade ='B';
              
               outfile <<name<<" "<<ssn<<" "<<grade<<" ";
              
              
               infile>>name;
           }
       }
}//MAIN
