hi, if i have a local variable as
A a;

in a class. I declare it in header and define/intialize it in the cpp file,
normally.

If I declare it as a global variable in my project, will that be initialized
at the point of declaraion?
thanks

Yes, globals are initialized before main or WinMain are called.

Chris:

What do you mean by "local variable in a class"?

Non-static (instance) member variable?

or

Static member variable?

Instance member variables are initialized with the object instance.

Static member variables are much like globals. As Scott says, they are
initialized before main() is entered.
