#include <sstream> #include <string> #include <iostream> int main() { std::istringstream one("one"); std::ostringstream two("two"); std::cout << "Before move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; *one.rdbuf() = std::move(*two.rdbuf()); std::cout << "Before move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; }
Résultat :
Before move, one = "one" two = "two" Before move, one = "two" two = ""
