Do you know what it's like to fall in the mud and get kicked... in the head... with an iron boot?
Of course you don't, no one does. It never happens. It's a dumb question... skip it.

Hey I need lots of money, how much can you offer?
System.IO.Path.IsPathRooted() does not behave as I would expect

Is better you ask about your problem not I need to a code.You can starting to write it and if you have problem then ask about your problem

You have several issues.
1 - this is the C++/CLI forum. If there's a place for C questions, it, by definition, is not here
2 - this sounds like a reasonably complex task. One has to ask how you got this far in your course, if you can't read.
3 - We're not here to do your homework, and if we did do it, you wouldn't be learning, now would you ?

And how it can be defined inside main ?
This question is out side scope of this forum. Rather ask in VC++[^] forum.

This forum is for Managed c++/cli
Your c question must be in Visual C++ forum here on CP.

I had written :
for(int i=0; i <10; i++){<br />
em[i]->pct = (gcnew System::Windows::Forms::PictureBox());<br />
em[i]->pct->Location = System::Drawing::Point(250, 250);<br />
em[i]->pct->Visible = true;<br />
em[i]->pct->Size = System::Drawing::Size(50, 50);<br />
}
And I got this error :
An unhandled exception of type 'System.NullReferenceException' occurred in Little tanks.exe
Additional information: Object reference not set to an instance of an object.
at this line : em[i]->pct = (gcnew System::Windows::Forms::PictureBox());
what did I do wrong?

How have you defined the em array?
|
|
|
|
|
em[i] is null, you probably created an array and didn't create the objects in it

the em array defined so : static array<tank^>^ em;
and tank is structure :
ref struct tank {<br />
int step_x, step_y; <br />
System::Windows::Forms::PictureBox^ pct;<br />
};
What do you mean saying to create objects for array?
|
|

thesad wrote: static array^ em;
You have not initialized array here.
Array can be initialized as given in MSDN example.
array<MyClass ^> ^ MyArray = gcnew array<MyClass ^>(100);

I wrote taht you had sad, but still at same line is that error
|
|
|
|

Would interesting to see, how you have done that. There are two possiblitites,
1. You have not allocated memory for it.
2. You are accessing invalid index.

Here, you had made couple of mistakes,
thesad wrote: array^ em = gcnew array(10);
array^ b_em = gcnew array(10);
Here, again you are defining local variables. It should be like this,
this->em = gcnew array<tank^>(10);
this->b_em = gcnew array<tank^>(10);
Again, simply defining array doesn't initializes its members, you need to allocate tank variable for each index. So, your code can be modified like this,
thesad wrote: for(int i=0; i <10; i++){
this->em[i]->pct = gcnew System::Windows::Forms::PictureBox();
this->em[i]->pct->Location = System::Drawing::Point(250, 250);
Modify this to,
for(int i=0; i <10; i++){
em[i] = gcnew tank;
this->em[i]->pct = gcnew System::Windows::Forms::PictureBox();
this->em[i]->pct->Location = System::Drawing::Point(250, 250);
