Question

please help. where there are // is where code needs to be written please help. Don't ask for better pictures this is the best they will get just enlarge them and you should be able to read them. thanks for any and all help!!!!

The file coursedata.txt, located in the folder Data on the c: drive, contains information on CSIT course enrollments for a certain semester. The data looks like this: CSIT 104 26 CSIT 104. 02 Decker 24 CSIT 473 Nazarenko CSIT 999 The data is organized into records. Each record contains the information for one course section, and includes, on separate lines: (l) the subject code and course number; (2) the section number: 3) the instructor's last name: (4) the enrollment for that section. Important: The records are ordered by course number, and the file ends with a "dummy record" for the nonexistent course, CSIT 999. Write a program to read the file and produce a report, showing the number of sections and total enrollment for each course. This report should be written to the file enrollment data, located in the Data folder on the C: drive. Here is a sample of what this report might look like: CSIT 104 74 24 CSIT 473 19

Explanation / Answer

#include<fstream>
#include<stdlib.h>
#include<string>
using namespace std;
int main()
{
   ifstream infile ("C:/Users/Surya/Desktop/coursedata.txt");//opening input file
   ofstream outfile ("C:/Users/Surya/Desktop/out.txt");//opening output file
  
  
  
  
   int count=0;
   int total;
   string current;
   string next;
  
   //reading first course
   getline(infile,next);
  
   while(next!="CSIT 999")
   {
       current=next;
       count=0;
       total=0;
       while(next==current)
       {
           count++;//incrementing course count...
           string n;
           getline(infile,n);//reading course number
           getline(infile,n);//reading MENTOR name
           getline(infile,n);//reading enrollments..
           int k,t=0;
           char c[1];
           //converting string to integer..
           for(k=0;n[k]!='';k++)
           {
               c[0]=n[k];
               t=t*10+atoi(c);//converting to int
           }
           total=total+t;//calculating total enrollments..
           getline(infile,next);//reading next couse data
          
          
          
       }  
       //writing to outputfile...
       outfile<<current<<" "<<count<<" "<<total<<" ";
      
      
   }
   //closing files..
   infile.close();
   outfile.close();
  
  
   return 0;
}
