Esempio

#include <sstream>#include <iostream>int main(){int n;   std::istringstream in;// could also use in("1 2") in.str("1 2"); in >> n;std::cout<<"after reading the first int from \"1 2\", the int is "<< n <<", str() = \""<< in.str()<<"\"\n";   std::ostringstream out("1 2"); out <<3;std::cout<<"after writing the int '3' to output stream \"1 2\""<<", str() = \""<< out.str()<<"\"\n";   std::ostringstream ate("1 2", std::ios_base::ate); ate <<3;std::cout<<"after writing the int '3' to append stream \"1 2\""<<", str() = \""<< ate.str()<<"\"\n";}

Output:

after reading the first int from "1 2", the int is 1, str() = "1 2" after writing the int '3' to output stream "1 2", str() = "3 2" after writing the int '3' to append stream "1 2", str() = "1 23"
