I've read a lot of the posts here giving profiling advice but I need to ask this.
From what I can tell, Visual C++ Express doesn't generate a debugging file that is used by profiler programs. I tried AMD Codeanalyst and it seemed to work fine except none of the routines in my program were identified -- just a lot of "unidentified modules".
I'm new to C++. I'm used to the simple profiler used by Python. Simple, I assume, because the language is interpreted.
I appreciate any insights.
P.S.: Is the rotation of the steering wheel the derivative of the rotation of the car?

A profiler is a tool that monitors the execution of another application. A common language runtime (CLR) profiler is a dynamic link library (DLL) that consists of functions that receive messages from, and send messages to, the CLR by using the profiling API. The profiler DLL is loaded by the CLR at run time.
Open the Performance Profiler by choosing Debug > Performance Profiler (or Alt + F2). For more information on using the CPU Usage or Memory usage tool in the Performance Profiler vs. the debugger-integrated tools, see Run profiling tools with or without the debugger.
Visual Web Developer Express is a freeware web development tool that allows developers to evaluate the web development and editing capabilities of the other Visual Studio editions at no charge.
When you start debugging in Visual Studio by selecting Debug > Start Debugging, or pressing F5, the Diagnostic Tools window appears by default. To open it manually, select Debug > Windows > Show Diagnostic Tools. The Diagnostic Tools window shows information about events, process memory, and CPU usage.
First, the polar angular velocity of the car should be proportional to the speed of the car and to the angular position of the steering wheel (to a first approximation).
Second, there's hardly a professor or blogger or book author who will tell you this, but if you want to see what the code is doing and optimize it, the hands-down simplest way is this.
Added: Programmers have a strong tendency to assume that any automated profiling tool will do a better job than the manual technique, but that depends on the details of exactly what they do. Most of them implement what's popular rather than what is most effective. The result is some performance problems being missed, putting a cap on the speedup you can get. Here is a list of common misconceptions that result in failing to find performance problems.
Some profilers do get it nearly right, including RotateRight/Zoom and LTProf.
