Question

As I understand the extraction operator>> is delimitered by whitespace. Does the extraction operator remove the delimiter from the stream? E.g., say I have the file

6
Foo
Bar

and the code

ifstream fin(filename);
int x;
fin >> x;

does the filestream still contain the newline character that followed the 6 (potentially messing up subsequent getline statements)? Or was this removed in the extraction process?

Answer 1

The part of the stream not consumed remains unchanged. So a subsequent call to getline will return an empty line.

If you are unsure about the exact file content, try cat -A filename.
