C++ Program to Demonstrate Use of Input String Stream

This C++ program illustrates use of input string stream. The class template std::basic_istringstream implements output operations on memory based streams. This is used to attach stream to a string, that is we can read from it using this stream.

Here is the source code of the C++ program which illustrates use of input string stream. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

    if(count > 0)

    string places;
```
```
 
```

    cout << "Enter the places you visited    : ";

```
    getline(cin, places);
```

    cout << "Printing the places you visited :-" << endl;

```
    print(places);
```
```
}
```

$ a.out
Enter the places you visited    : USA Germany London India
Printing the places you visited :-
1. USA
2. Germany
3. London
4. India
You have visited 4 places!
