Hi all,
can anyone tell me the syntax of declaring a
2D array of function pointers.... and initializing it..
thanks

Just the same as a 2D array of any other type. Start with a typedef for
the function pointer type.

return_type (*fcn_array[ dim1 ][ dim2])( arg_list);
Initialize it as you would any other 2d array.

See why I suggested a typedef :)

I actually don't find the syntax to be excessively horrid, though maybe
I'm just perverse when it comes to these things. :)
Nonetheless, I agree that a typedef is probably the sensible approach
since in practice the function pointer type is likely to be used elsewhere.

Hello,
I have encountered a strange problem and I hope you can help me to
understand it. What I want to do is to pass an array of chars to a
function that will split it up (on every location where a * occurs in
the string). This split function should allocate a 2D array of chars
and put the split results in different rows. The listing below shows
how I started to work on this. To keep the program simple and help

A question about void*. I have a hash library where the hash create

Hi,
Like almost all of beginners I have problem understanding pointers.
Please, look at this piece of code, and please explain me why myswap
function doesn't work as it's supposed to do, whereas myswap2 is doing
exactly what I want it to do - swaping pointers. Where I made a mistake?
Thanks

For the record, not a student, just someone attempting to learn C++. Anyway, the problem I'm having right now is the member function detAddress, of object controller.
This is more or less, your standard dynamic address book program. Adding, and listing work just fine. However, deleting, editing and viewing relies on member function retAddress. This function returns an array of pointers that are pointing to created objects. In action, all it...

Hi,
Im trying to migrate from programming in Matlab over to C. Im trying
to make a simple function to multiply one matrix by the other. I've
realised that C can't determine the size of a 2d array, so im
inputting the dimensions of those myself.
The problem is that the output array (C=A*B) has as many rows as A and
as many columns as B. I would think of initialising C with:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
