hi every ; i want to know how to start simulation using c++ , i searched in many websites in order to find some hints about this subject but i found nothing .
Best regards

Simulation is a far too general term. What kind of simulation? What kind of system do you want to simulate? If you're talking about a dynamic system (i.e., differential equation of motion), then at the base all you need is some good numerical integrators library, then probably some linear algebra library, and then you just implement the functions that compute the time-derivative of the state vector and feed it to an integrator, that's it. If it's a more complex system, you might need quite a bit of code to model the dynamics of that system (instead of manually writing out the complete differential equations).

There are certainly simulation tools written in C++, but these are very complex, and specialized, bits of software - not something you just go out and write in a day or three. As Mike_2k said, what kind of system do you want to simulate? If you can get into some specifics, we may be better able to suggest some tools to try.

thank you all , i want to simulate the e- commerce starting from the autheticatin server in which the website and the bank are registered then the simulating the web site that contains the itemes to be sold and the payment method until the whole procedure ends.
this is just a start after that i want to add some risk analysis ,decisssion rules and prediction .

Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...

When I execute this progammatically, I get a table with row heights much larger than when I do this manually.

Note : Sel is the Word.Selection object and the Clipboard contains an Excel Table.

public void AddClipboard()
{
Sel.PasteExcelTable(false,false, false);
var t = Sel.Tables[Sel.Tables.Count];
t.AutoFitBehavior(Word.WdAutoFitBehavior.wdAutoFitContent);
}

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...
