How do i create multiple files in/from ofstream?

Hello everyone,I have a question on file manipulation and would like to know how
could i create multiple files from ofstream. For example in the code below when option 4 is selected a file is created called "Progress.txt" but i want to know how to enable the program to create a new file like "Progress1.txt" instead of just overwriting the old existing one,kinda like a database but i do not want to rewrite the information in the old file instead i want a new file created with the new information stored in it (Keeping records).I do not know how to do that in code form.

// fstream::open
#include <fstream>
using namespace std;

int main () {

  fstream filestr;

  filestr.open ("test.txt", fstream::in | fstream::out | fstream::app);

  // >> i/o operations here <<

  filestr.close();

  return 0;
}


If there isn't a file called test.txt, fstream::app creates one.

Thank you for responding . But instead overwriting i want it to create a new file everytime the option is choosen,so first time i run it i creates test.txt but the next time i run it i want it to create a new file called test1.txt and so on...
