### istringstream

```cpp
string str1 = "test";
string str2 = "test";

```

### ostringstream

```cpp
string str1 = "test";
string str2 = "test";

```

### stringstream妙用：（以上两个功能都具备）

数据类型转换：

```cpp
string str1 = "test";
string str2 = "test";

```

string转double/int:

```cpp
string str1 = "test";
string str2 = "test";

```
