(b) Ignores new line character 10 times.
(c) Ignores up to 10 characters until encountering a new line character.
(d) Ignores 10 new line characters.

Answer 1

The function ignore(10,'\\') in C++ ignores up to 10 characters or stops at a newline character, whichever comes first.

Step-by-step explanation:

The statement ignore(10,'\\') is used in programming, and it is a function of input streams in C++. Specifically, the function ignores characters in the input buffer. The correct answer to what ignore(10,'\\') does is (c) Ignores up to 10 characters until encountering a new line character. What this function call does is it instructs the input stream to discard up to 10 characters or stop earlier if a newline '\\' character is found. This is useful for clearing input buffers between reading different pieces of input.
