Question

Here is my program so far:

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

enum sortType
{
   FIRST=0, LAST=1, GPA=2
};

const int SIZE = 1000;

struct studentType
{
   string fname, lname, major;
   int id;
   float gpa;
};

//void sortStudents(studentType student[], const int SIZE, sortTypefield);


int main()
{
   ifstream fin("program7.txt");
   ofstream fout("output7.txt");
   int count;

   studentType student[SIZE];

   int i=0;

   while(i<SIZE && fin >>student[i].fname >> student[i].lname >>student[i].id
       >> student[i].major>> student[i].gpa)
   {
       i++;
   }

   count = i;

   for(i=0;i<count;i++)
   {
       fout << setw(15)<< student[i].fname
       << setw(15) <<student[i].lname
       << setw(15) <<student[i].id
       << setw(10) <<student[i].major
       << setw(5) <<student[i].gpa << endl;
   }

   return 0;
}

I am trying to write a sort function that will sort the data byfirst name or last name (if I can figure out how to sort by one theother should follow pretty easily. I am trying to use anfunction similar to this:

void sortStudents(studentType student[], const int SIZE, sortTypefield)
{
   int i, j, min;

   for(i=0;i<SIZE;i++)
   {
       min = i;
       for(j=i+1;j<SIZE;j++)
       {
           switch(field)
           {
           caseFIRST:
              if(student[j].fname <student[min].fname)
              {
                  min=j;
              }
              break;
           caseLAST:
              if(student[j].lname <student[min].lname)
              {
                  min=j;
              }
              break;
           caseGPA:
              if(student[j].gpa <student[min].gpa)
              {
                  min=j;
              }
              break;
           }
        }
       swap(student[i],student[j]);
   }
}

but it seems like I can't get the loop to run to sort mydata. Any help you would appreciated and if you need me toclarify anything I will gladly do so. I know I don't use anycomments or anything in my code but I like to get it done thenexplain things after. Thanks in advance for your help!
