Segmentation Fault in an input/output array

[Feymanismyhero]

when I try to run the code, I get a segmentation fault core dumped
it returns 139 (0x8B)
the file it is pulling from is a list of numbers, but without the string, the output ends up going from values of ~70,000 to values around 50

#include <iostream>
#include <fstream>
#include <cstdio>
#include <cstdlib>
#define MAX 29656
using namespace std;
string el[MAX];
ifstream file1("results.txt");
ofstream file2("Energy1.txt");
ofstream file3("Px1.txt");
ofstream file4("Py1.txt");
ofstream file5("Pz1.txt");

ofstream file6("Energy2.txt");

ofstream file7("Px2.txt");
ofstream file8("Py2.txt");

ofstream file9("Pz2.txt");

void input()
{
   for (int n=1; n<=MAX; n++)
   {
      el[n]=file1.get();
    }
}
void output()
{
    for (long long i=1; i<=MAX; i++)
    {
       int j=i%8;
       if (j==1)
       {
           string E1= el[i];
            file2 <<E1 <<endl;
        }
        if (j==2)
        {
           string Px1= el[i];
           file3 <<Px1 <<endl;
        }
        if (j==3)
        {
            string Py1= el[i];
            file4 <<Py1 <<endl;
         }
        if (j==4)
        {
             string Pz1= el[i];
             file5 <<Pz1 <<endl;

That's pretty much unreadable as presented. Can you:
1. Format your code using the format tags and ensure it's indented in a reasonable manner.
2. Remove calls to open/close on streams, it's wrong and distracting.
3. Don't check a stream if it's open, check if it's good. For example:

std::ifstream f1(filename);
while (f1) // test for good
{
   // do stuff with f1
