Erm, guys. No operator "+" matches std::string + int. You have to explicitly convert int to string and then concatenate it using +. #include <iostream> #include <sstream> #include <string> int main() { std::stringstream obj; std::string test = "test"; int integer = 39; obj << integer; std::string test2 = test + obj.str(); std::cout << test2; return 0; }
