Question

The statement:

cin >> setw(10) >> str;

will read up to this many characters into str.
A) Nine
B) Ten
C) Eleven
D) Eight
E) None of these

Answer 1

The correct answer is B) Ten. The C++ statement with cin and setw(10) reads up to ten characters into the string variable str. It may read fewer characters if it encounters whitespace or EOF before reaching ten characters.

Step-by-step explanation:

The statement: cin >> setw(10) >> str; is a C++ statement that utilizes the input stream and the setw manipulator to control input formatting. When used in this context, setw(10) specifies that up to 10 characters will be read into the string str. However, it's important to note that the '>>' operator stops reading input upon encountering whitespace, EOF, or after extracting the specified number of characters (in this case, 10). So the correct answer is B) Ten, meaning str will contain up to ten characters, potentially fewer if whitespace or EOF is encountered before ten characters are read.
