Final answer:
The statement that cin stops reading input at a newline character is false; cin typically stops reading at any whitespace. The getline function, in contrast, stops reading at a newline character.
Step-by-step explanation:
The statement about the behavior of the cin statement is false. The cin object in C++ will stop reading input when it encounters whitespace, which includes spaces, tabs, and newline characters if used with the extraction operator (>>). This is standard behavior for formatted input in C++, used to read variables like integers, floats, strings, etc.
However, it is possible to change this behavior or to use functions like getline(), which reads a line of text and stops at the newline character. The behavior described in the question more closely resembles the behavior of getline rather than the default behavior of cin with the extraction operator.
