Exemplo
#include <iostream>
#include <sstream>
int main()
{
// default constructor (input/output stream)
std::stringstream buf1;
buf1 << 7;
int n = 0;
buf1 >> n;
std::cout << "buf1 = " << buf1.str() << " n = " << n << '\n';
// input stream
std::istringstream inbuf("-10");
inbuf >> n;
std::cout << "n = " << n << '\n';
// output stream in append mode (C++11)
std::ostringstream buf2("test", std::ios_base::ate);
buf2 << '1';
std::cout << buf2.str() << '\n';
}
Saída:
buf1 = 7 n = 7
n = -10
