Re: function template specialization used with default parameter

2009-01-07T17:48:38Z

I was unsure what happens to the missing argument in that case. Leandro
mentioned 14.8.2.4 where the default value is apparently carried over to
the specialisation.
I am not sure I understand that statement, sorry.
When you mention the Standard, it's useful to give at least the relevant
subclause or a quote from it. Not necessary, of course, but useful.

If the destructor does nothing, you could just omit it.
What would be the use of this function? What is the role of the
argument? And what is the purpose of the class TheDate? What design
requirements do you have for it? They usually stem from the intended
use of the class. How is an object of that class going to be used?

Neither do we. This is a language newsgroup, and as I've told you, the
'fx' (as you put it) is *not* from the Standard library.
_strdate_s isn't from the Standard library either, BTW

Your instructor probably has. Do you even have an instructor?
Someone? Your fellow student? How much do they know?

Re: Can C++ be used to write programming languages?

2009-01-07T17:32:03Z

C++ is nearly a strict superset of C. Therefore anything one can do in C can
be done in C++. (There are some minor incompatibilities but they are not
relevent as they have no impact on capability, and C99 has some features not
included in C++, but they are merely convenience features, and have no real

Perhaps you are not familiar with the language used by the author?
Along the same line, you may note that huge chunks of C++ sometimes look
like C.
Dinkumware is the best reference site for this kind of thing that I know of.

Re: Obtaining number of seconds since Jan 1 1970.

2009-01-07T17:12:49Z

You have two problems:
1- find what is the current time.
2- compute the number of seconds between the current time and 1/1/1970.
The second step can be implemented portably.
The first one cannot, unless you use the universal device:
std::cout<<"What time is it? enter YYYY MM DD HH MM SS"<<std::endl;

So, where can I get me one o' them Z8000 beasties?
Some companies do stamp out old cores in new microcontrollers; I wonder
whether Z8000 is still in use. It seems like the high-end cores of
yesteryear are just place-able macros nowadays, like any other block of
random logic.

Re: function template specialization used with default parameter

2009-01-07T16:53:23Z

I got the int version.
It seems that the default argument from the original version is
carried on to the specialization. Could it be?
There's a paragraph of the Standard related to the deduction of
template type parameters. Although it's not the exact same case,
there's an example quite similar to the one in this post. Notice that

Obtaining number of seconds since Jan 1 1970.

2009-01-07T16:53:18Z

Is there some portable way to obtain the number of seconds since the
start of January 1st, 1970? I don't have a copy of the C++ standard in
front of me, but C99 states:
[7.23.2.4/2] "The time function determines the current calendar time.
The encoding of the value is unspecified."
I'm assuming C++ didn't introduce any additional restrictions.

this seem to be working better... i have the system date in a char
array.(it's the only way i could find) .. char dateBuffer1[10] i
need to get to std::string theDateBuffer ..any ideas?
class TheDate
{
public:
TheDate(std::string initialDateBuffer);
~TheDate();
std::string GetDateBuffer();
