Question

Which header file is used to pass unknown number of arguments to function?

(a) stdlib.h

(b) string.h

(c) stdarg.h

(d) stdio.h

I had been asked this question in class test.

I want to ask this question from Unspecified Number of Arguments in section Functions, Namespaces & Exceptions in C++ of C++

Answer 1

Correct option is (c) stdarg.h

The best I can explain: Because the cstdarg defines this header file to process the unknown number of arguments.
