      min = i;
    if (a[i] > a[max])
      max = i;
  }
  int tmp = a[max];
  a[max] = a[min];
  a[min] = tmp;

Answer 1

There are three options.
1. Find a library for working with Excel. The smallest and open source is libxlsxwriter.
2. Save in simpler formats. The simplest of them is CSV. Don't forget that Russian and English Excel work with different CSVs.
3. Use Excel OLE automation.
Spolsky has an article why M$ Office formats are so complicated: https://rutlib5.com/book/25666/p/27

Answer 2

Perhaps for you there will be a solution - recording the result in csv format. Files of this format are opened by default through Excel.
