My program can't read all the data from a file

My program can't read all of the data from my MarvelIn.txt file. It reads about 29 spaces in, and MarvelIn.txt contains only 9 entries, then I get a runtime error. I think I have all the syntax right, however this is the only error I have. It will not output to the output file "MarvelOut.txt".

here is the code:

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


struct sstruct
{
string first, last;
string department;
int salary;
};


 void init2(sstruct s[50])
{
int maxarray = 50;
sstruct init = { "Darth", "Vader", "None", 0 };

for (int i = 0; i < maxarray; i++) {
s[i] = init;
cout << "init: " <<s[i].first<<endl;
}
}

void read(sstruct s[50], int &nums)
{

int maxarray = 50;
ifstream inf("MarvelIn.txt");
int i=0;
  while (!inf.eof())
  {
    inf >> s[i].first >> s[i].last >> s[i].department >> s[i].salary;
    cout << "read: "<<s[i].first<<s[i].last << s[i].department << 
  s[i].salary << endl;

    i++;


     }

   nums = i;


   }

   void avg(sstruct s[50], int &nums, double &average2)
    {
   int maxarray = 50;
   int i;
   for(i=0;i<nums;i++)
    average2 += s[i].salary;
    average2 /= nums;
   }


 void print(sstruct s[50], int nums, double &average2)
 {
 int maxarray = 50;
 ofstream outf("MarvelOut.txt");
 int i=0;
 string temp;

 outf<<"the number of professors is: "<<nums<<endl;

 cout<< "the number of professors is: " << nums << endl;
outf<<endl<<"The average salary of the professors is: "<<average2<<endl;
outf<<"Advisor                    "<<"Major     "<<" Department     " 
<<"Salary     "<<endl;
for(i=0; i < nums ; i++)
{
    temp= s[i].last + "," + s[i].first;

    cout << "last, first " << temp << endl;
     outf<<left<<setw(20)<<temp<<right<<setw(5)<<s[i].department
            <<setw(5)<< s[i].salary<<setw(8)<<endl;
}
   outf<<endl<<endl;
 }
    void swap(sstruct &a, sstruct &b)
    {
   sstruct temp;
   temp=a;
   a=b;
   b=temp;
   }


void bubbleSort(sstruct s[50], int &nums)
{
int maxarray = 50;
 int i, j;
 bool swapped;
  for (i = 0; i < nums-1; i++)
 {
 swapped = false;
 for (j = 0; j < nums-i-1; j++)
 {
    if (s[j].department > s[j+1].department)
    {
       swap(s[j], s[j+1]);
       swapped = true;
    }
 }

 // IF no two elements were swapped by inner loop, then break
 if (swapped == false)
    break;
   }
  }


int main(){

 int nums=0;
  double average3=0.0;

 const int maxarray = 50;

sstruct s[maxarray];

init2(s);

print(s, nums, average3);

read(s, nums);
cout << "numsfirst: " << nums << endl;


avg(s, nums, average3);

cout << "nums" << nums << endl;

bubbleSort(s,nums);

 print(s,nums,average3);

return 0;
