[Bearbeiten] Beispiel
#include <sstream> #include <iostream> int main() { int n; std::istringstream in; // could also use in("1 2") in.rdbuf()->str("1 2"); // set the get area in >> n; std::cout << "after reading the first int from \"1 2\", the int is " << n << ", str() = \"" << in.rdbuf()->str() << "\"\n"; // or in.str() 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); // C++11 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"
