I guess most of you who have worked with C/C++ have an intuition of how the preprocessor works (more or less). I thought so until today, but my intuition was proved wrong. Here is the story:
We know t开发者_开发百科hat in-line are favorable as they are checked by the compiler and same operation ( like ++x ) does not evaluate more than once when passed as an argument as compared to macros.
I\'ve got a sample code from MSDN and I\'ve found code syntax I\'ve never seen before: namespace Mvc3RemoteVal.Controllers
I try to get at the first actual parameter sent to a variadic macro. This is what I tried, and which does not work in VS2010:
I have a method DoSomething() defined in my AppDelegate. This is the full implementation of my appDelegate:
In my iPhone app, I have this in my .h file #define ORIENTATION_IS_PORTRAIT UIDeviceOrientationIsPortrait([[UIDevice currentDevice] orientation])
I have a few dozen of these types of structs and I\'m hoping there is a clever way of generating the operator<< methods using macros or template meta-programming.Please also notice that endianes
This question already has answers here: Closed 12 years ago. Possible Duplicates: what is the difference between #include <filename> and #include “filename”
I am doing some template meta programming, mostly just writing my own compile time list, but I also have some preprocessor magic which I want to use to make things easier if possible.
In discussing design possibilities for a project that has a very large number of constants and bit patterns to be defined, the question came up about how many #defines can a standard compiler handle?I
