simulation using c++

[tooota]

Hi all , this is my first post , and i want to know how to start simulation using c++ , i have no background in simulation ,if there is any books tutorials ,any thing that helps ;let me know .
thank you very much.

What do you want to simulate? Real world application or just for fun?

I think you need to be more specific;
Simulation of -?
- Physics
- Biology
- Chemical reactions
- Mathematical formulas (graphics)
- Evolution
...

i think simulation which "tooota" talks about must be connected with robotics .

like soccer simulation or rescue simulation leagues !

i want to simulate the whole procedure of e-commerce ; starting from the authentication server in which the client and the bank were registered, so i don't know how to simulate the authentication server as a start !!!!.
thank you

What are you trying to accomplish with your simulation?
Performance modeling?

In performance modeling, a simulated object represents the performance characteristics of an object in the real world. For example, in simulating an authentication server, the simulation object does not actually do authentication, it simply accumulates the resources used by a transaction.

e.g. A "register user" transaction might do a DB lookup, encrypt several data items, then do one or more DB writes. The cost of each of these operations can be measured, or if it's a new application, estimated in terms of CPU cycles and disk wait time.

One also needs to know, or project, the transaction arrival rate at the authentication server. From this, the simulation model can predict how many authentication servers are needed.

first thanks to all, second : my idea is to build e-commerce educational tool that contains the items would be sold,the payment method,and fund transfers.then to add risk analysis ,prediction and extract a decision rules
I'm so confused , any ideas ,explanation will be appreciated.
