Question

Which function is used to read a single character from the console in C++?

(a) cin.get(ch)

(b) getline(ch)

(c) read(ch)

(d) scanf(ch)

I have been asked this question in an internship interview.

This key question is from Basics topic in section Basics Concepts of C++ of C++

Answer 1

The correct answer is (a) cin.get(ch)

To explain I would say: C++ provides cin.get() function to read a single character from console whereas others are used to read either a single or multiple characters.
