Question

To use command line arguments in C++, how many parameters are passed to the main function?

(a) 1

(b) 2

(c) 3

(d) 4

I have been asked this question during an interview for a job.

Question is taken from Command Line Arguments topic in chapter C++ Advanced of C++

Answer 1

The correct answer is (b) 2

The explanation is: 2 arguments are needed to be passed to main() function while using command line arguments. The first one represents a number of strings in the argument list and the second list represents the list of string arguments.
