RE: How to pass 2D variable-sized arrays in C++?

["Quang Nguyen (Ngo)" <quang dot nguyen at tapeware dot com>]

Hi Jason,

Try this:

void func(int c, int r, float f[][])
        {
        printf("hello\n");
        }

main()
        {
        int c = 5, r = 7;
        float f[r][c];

        func(c, r, f);
        }

Hello,
How does one type the 2D variable size array "f" below?
I've tried nasty casts that all get rejected, cheating
with void, etc, etc.  Very stumped!  Sure, I could back
up to a real float** and manually new[] and pass float**,
but that takes all the fun out!

Thanks,
Jason


void function(int c, int r, ??? f )
{
}

main() {
  int c(5), r(7);
  float f[r][c];
  function(c, r, f);
};
