Compile time error for size parameter in templates

Hi,

The following code doesnt seem to compile

template <typename Type, int size>
Type min(Type (&arr)[size])
{

}

The error says
error C2265: '<Unknown>' : reference to a zero-sized array is illegal

Any suggestions

Thanks.

The problemis that min might be already defined as a macro.

try

#undef min
template <typename Type, int size>
Type min(Type (&arr)[size])
{
}

Or use an other name for min like mymin, xmin or whatever.

Doesnt seem to help. I changed the name of the function to min1 and it still gives the same error.

The following code compiles fine on VC 2005

template <typename Type, int size> Type Min(Type (&arr)[size])
{
return ' ';
}

int main()
{
char y[10];
Min<char, 10>(y);
return 0;
}

Hi Nishant,

I copied your exact code and it doesnt compile on Visual C++ 6.0,

Anyways,

Thanks all for the response.

Okay - VC 6 is pretty bad at handling some of the template related stuff. Upgrade to VC++ 2005 if you can, it's definitely worth it.

Kevin,
Sorry I should of replied to you. I replied to Nishant instead. But the point is that the same code doesnt compile on Visual C++ 6.0

I believe the reason for your problem is stated in the error message:

"reference to a zero-sized array is illegal".

Make sure that you are passing in an array with well defined, non-zero size. See Nish's code abover for an example.

Forget VC6 and templates. It has horrible problems use the 2003 or 2005 compilers. The code you are asking for works on both.
