file creation in C++

[alirezan1]

Hi guys,

I want to write a code in C++ that creates files with different filenames like this:

file1: test1.txt
file2: test2.txt
...
file38: test38.txt
...

It has to be in a loop that generates different file eachtime.

can anybody help?

thanks

#include <sstream>
#include <fstream>
#include <string>
using namespace std;

string itos(int i){
	stringstream s;
	s << i;
	return s.str();
}

int main(){
	string fname = "file", ext = ".txt";
	int someNum = 10;
	for (int i=0; i<someNum; i++){
		fname += itos(i) + ext;
		ofstream out(fname.c_str());
		out.close();
		fname = fname.substr(0,4);
	}
		  
	return 0;
}

This works, but it's pointless.

Hi,

thanks for the code, but it is not pointless. I have to do a project that requires this feature(I have no choice but to do what project owner wants!)

Thank you very very much for the code.
