Ive decided to start learning standard c++, and have stumbled upon a problem. I would Like to use a timer to time how long the program is running, but not based of the cpu speed. isn't there like a way to call from the system clock?

well if you use the SDK (which happens to the forum your on) then there should be a timer function in the documentation. Otherwise you'll have to figure out some way to access the clock directly from the system, which i don't know how to do in regular c++.

Aside from the ones in the GSDK, there is also the C function time, or you can call the API function.

I'm going to go out on a limb and guess that you are using windows... so you can use GetTickCount() to return the time your program has been running in milliseconds.

I believe it is windows.h... it is automatically included when I compile in Visual C++ 2005... not sure about the compiler/ide you are using.

From MSDN:

Quote: "The GetTickCount function retrieves the number of milliseconds that have elapsed since the system was started"


To get the amount of time your program has been running, you can record the value from GetTickCount() at the very start of your program. Then when you need to know how long is has been running, you call GetTickCount() again and subtract the first value - that's the answer in milliseconds.

Oh, and the dbTimer() function is simply a rename of the GetTickCount() function.

oh and, in c++, theres no need to have the header files after compiled to run, is there? for example, i make a program that uses iostream.h and give the exe to a friend, does he need iostream.h on his pc?

Nope, header files are only used during compiling.

.lib files are only used during linking.

No once its compiled into a PE there's no need to bundle the header files with it.

I know the voices aren't real, but they have good ideas!
