Open a output stream and send to it.

#include <iostream>
#include <string>
#include <fstream>

int main()
{
	std::ofstream output;
	std::string str;
	
	output.open("file.dat");

	if (output.fail()){
		std::cerr << "File creation failed.\n";
		return 1;
	}
	
	std::cout << "Enter name: ";
	std::getline(std::cin, str);
	output << str << std::endl;


	output.close();
	return 0;
}
