std::ostringstream is an STL output stream interface for std::string manipulation.

In the example below, int and std::string are appended to a std::ostringstream, before the std::ostringstream is finally converted to std::string.


#include <iostream>

#include <sstream>



int main()

{

  std::ostringstream s;

  const int first_digits = 123;

  const std::string dot = ".";

  const int last_digits = 456;

  s << first_digits << dot << last_digits;

  std::cout << s.str() << '\n';

}
