C++ Programming - Functions - Discussion

There are certain rules for providing default values to arguments:

(1) You cannot have a default argument followed by non default argument.

(2) If you default an argument then you will have to default all the subsequent arguments after that.

(3) You cannot have a default argument in the middle of the list.

Yes Answer (B) is correct because default value can be provided to the trailing of the argument list.

What is training ?

Statement B is too vague. Take a look at this function:

int func1 (int parm1=10, int param2=20, int param3=30);

There - I just provided a default value to the middle parameter.

I would reword it to this statement:

We can provide a default value to a particular argument in the middle of an argument list where any following arguments do not have a default value.
