How can I check the size of an unsigned in the preprocessor under g++? sizeof is out of the question since it is not defined when during preprocessing.

I want to learn C++ by using Vim and MinGW as compiler. I'm interesting at "C++ Primer (4th Edition)" and "C++ Primer Plus (5th Edition)" but I don't know how about it different. It has no book store that I can review those books, so I want to know, what is the different between those book and which…

Ok, so I don't want you to do my homework for me, but I'm a little lost with this final assignment and need all the help I can get. Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This…

Prototype : void read ( const std::string &imageSpec_ )
I call this function from managed c++ dll by passing a std::string.
When i debug the unmanaged c++ code the parameter imageSpec_ shows the value correctly…

After more than a few questions about deciding on C++ books I thought we could make a better community wiki version. Providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate…

The only pre-process directive that I know about in VBScript / Classic ASP is the #include. I don't know if that is the official name but I'm basically looking for code that can execute code or other instructions before the general VBScript.
Are there any other such directives in VBScript? Such as…

We have set-up a simple versioning system for our builds to ensure the built files always indicate whether they are Beta Debug or Beta Release builds
I moved the file version info to to myapp.rc2 and created version.h
// version.h
// _DEBUG is defined by VS
#define _BETA
#ifdef…

Can you write preprocessor directives to return you a std::string or char*?
For example: In case of integers:
#define square(x) (x*x)
int main()
{
int x = square(5);
}
I'm looking to do the same but with strings like a switch-case pattern. if pass 1 it should return "One" and 2 for "Two" so…

Hello, I'm making a simple compiler for a simple pet language I'm creating and coming from a C background(though I'm writing it in Ruby) I wondered if a preprocessor is necessary.
What do you think? Is a "dumb" preprocessor still necessary in modern languages? Would C#'s conditional compilation capabilities…

The preprocessor in C and C++ deserves an entire essay on its own to explore its rich possibilities for obfuscation.
It is true that the C++ (and C) preprocessor can be used for a lot of powerful stuff. #ifdefs and #defines are often used to determine platforms, compilers and backends. Manipulating…
