I'd like to make a tree without any functions. I mean just using the
structure.
I have a structure:
struct TTree
{
int key;
struct TTree* pLeft;
struct TTree* pRight;
} Tree[] =
{
??????????
}
In the place with quastions I should write something for making a
tree. (Any tree). I just need to know how is it possible. I wrote
something like
struct TTree
{
int key;
struct TTree* pLeft;
struct TTree* pRight;
} Tree[] =
{
5, Tree[3], Tree[6],
4, NULL, NULL,
6, NULL, NULL
}
It didn't work. 2 3180

struct TTree { ... };
static struct TTree node4 = { 4, NULL, NULL }, node6 = { 6, NULL, NULL };
static struct TTree node5 = { 5, &node4, &node6 };
struct TTree *Tree = &node5;
This is assuming you want your Tree variable to be a pointer and not the
root node itself. I.e. if you want to be able to change which node is
the root node. Otherwise you could rename node5 to Tree.

Nit picking: How do you print it without any functions?
Try this:
#include <stdio.h>
struct TTree
{
int key;
struct TTree* pLeft;
struct TTree* pRight;
} Tree[] =
{
/* Tree[0] */ 5, &Tree[1], &Tree[2],
/* Tree[1] */ 4, NULL, NULL,
/* Tree[2] */ 6, NULL, NULL
};
int main(void)
{
puts("Tree Program");
return 0;
}

I have following structure in c++.
typedef struct MMF_result_struct
{
int action;
char text;
int cols,rows;
int month,day,year;
} MMF_result;
Now this structure is shared between C++ and C# using memory mapped file. We already have C++ code for handling memory mapped file. I am working on converting code for memory mapped file in C#. Now I have to pass pointer to the above structure. I converted this structure to C# as follows:

From my VB program I call a C++ function that gets a structure pointer

My problem is that each 'double' fields get 12 bytes instead of 8 so
the structure length results wrong.

Can anyone suggest how I would marshal a variable length structure back from
an API call. Specifically, I am looking at the WaitForDebugEvent function,
which returns a DEBUG_EVENT structure.
However, the DEBUG_EVENT structure is defined as a union, and the size and
contents vary depending on the event code contained in the header.
typedef struct _DEBUG_EVENT {
DWORD dwDebugEventCode;
DWORD dwProcessId;

I have adapted the following code from the MSDN help for PropertyInfo
SetValue. In the original code, the structure MyStructure is defined as a
class MyProperty, and it works as expected. There is also a minor change in
class Mypropertyinfo, which I have commented out.
When using a structure, however, the second call to GetValue returns
"Default caption". Can anyone tell me why, and how I can make this work?

Hi Willy,
Thank you very much for your work.
C++ code doesnot make any serialization.
So at runtime C# code gives an serialization error at
"msg_file_s sa = (msg_file_s) bf.Deserialize(ms);"
I thought that it is very hard to memory map structure array.
I need both read and write memory mapped file at both side of C# and C++.

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.
