If you have an array...

   int x[100];

.... you can print the 50th element using...

   std::cout << x[49] << '\n';

Consider using a for loop to make the index variable.

#include <fstream>

using namespace std;

#define SIZE 5

int main()
{
      ofstream outArray;
      char array[SIZE];

      array[0]='a';
      array[1]='b';
      array[2]='c';
      array[3]='d';
      array[4]='e';

      outArray.open("array.txt");
      

      for(int i=0;i<SIZE;i++)
            outArray << array[i] << endl;
      outArray.close();

      return 0;
}
