Question

What we can’t place followed by the non-default arguments?

(a) trailing arguments

(b) default arguments

(c) both trailing & default arguments

(d) leading arguments

The question was asked during an interview.

This is a very interesting question from Default Arguments in division Functions, Namespaces & Exceptions in C++ of C++

Answer 1

The correct answer is (b) default arguments

Easy explanation - To avoid the ambiguity in arguments.

eg. if func(int a=3, int b);

so if we call func(5), here will 5 will be value of a or b, because 5 is first parameter so a should be 5  but as only one argument is given b should be 5. So to remove such ambiguity default parameters are kept at the end or rightmost side.
