so I'm taking in input by

```
string input,word;
while(getline(cin, input)) {
 stringstream ss; 
 ss<<input
 while(ss >> word)
 ...

```

and printing the stuff I want by
 `cout <<word<<" ";`

However, when I do this it creates an extra whitespace at the end of each line and I don't want that. If I don't put that whitespace there there will be no spaces between words when I print them out. Is there an easier way to cout the words I want so that they are automatically spaced? What are some of the things I could do to prevent the extra whitespace at the end of each line.
