stringstream >> operator not space delimitating

[aoeuhtns]

I am using a stringstream, but when I try to read out items into a string, it reads in by line not ' ' delim as I expect the behaviour to be.

stringstream ss;
string inputBuffer, stringBuffer;
getline(cin, stringBuffer);
ss << stringBuffer << '\n';
ss >> inputBuffer;

If stringBuffer is "This is a string", my inputBuffer gets "This is a string" not "This" as I expect.

Your target type is a string. stringstream::o perator>> will read data and format it to the target type. In this case a string.

What deliminator are you talking about? The one for get? There is no deliminator for stringstream::O perator>>.

I guess, to my understanding (which could be wrong), the >> operator is supposed to just get an item not a line. An item being until it finds a whitespace character (so, a space in this case). But when I use it, the >> acts as a getline function.

That is correct.

If the data is 12G 4, then a >> to an int will get 12. A following >> to a char with get G and a following >> to a short will get 4.

However, a >> to a string will get 12G 4 because every byte of data is valid in a string.

The reason cin >> stops on whitespace is due to the fact that istream::operat or>> does not have a overload that takes a string&. The reason scanf stops on whitespace is that none of the built-in types contain whitespace as a value (in C a string is not a type. In C++ it is).
