The s of this class mantain internally a pointer to a stringbuf object that can be obtained/modified by calling member ruf. This streambuf-derived object stores a sequence of characters (string) that can be obtained/modified by calling member str. */ //使用(C++庫)ostringstream輸出(格式化) //simple example #include #include #include using namespace std; void test() { //ostringstream oss; //oss.str("abc"); ostringstream oss("abc"); cout << oss.str() << endl; oss << 8 << endl; oss << 3.14 << endl; oss << " ok ." << endl; cout << oss.str() << endl; oss << 8 << " " << 3.14 << " " << " ok ." << endl; cout << oss.str() << endl; } int main(int argc, char* argv[]) { test(); return 0; }
