I'm currently working on a very large project, and am under a lot of pressure to finish it soon, and I'm having a serious problem. The programmer who wrote this last defined variables in a very odd way - the config variables aren't all in the same file, they're spread out across the entire project of over 500 files and 100k+ lines of cod...
I've written a .cpp file with a number of functions in it, and now need to declare them in the header file. It occurred to me that I could grep the file for the class name, and get the declarations that way, and it would've worked well enough, too, had the complete function declaration before the definition -- return code, name, and par...

Why, then, does the following code give me a linker error? #include <algorithm> #include <iostream> class test { public: static const int N = 10; }; int main() { std::cout << test::N << "\n"; std::min(9, ...
In C++, I have a certain template function that, on a given condition, calls a template function in another class. The trouble is that the other class requires the full definition of the first class to be implemented, as it creates the second class and stores them and manages them in similar fashions. The trouble is that naturally, they...
While I was reading the accepted answer of this question, I had the following question: Typically, methods are defined in header files (.hpp or whatever), and implementation in source files (.cpp or whatever). One of the main reasons it is bad practice to ever include a "source file" (#include <source_file.cpp>) is that its methods imp...

I haven't been able to find a reference that defines what these methods are made up of. I kind of get what these methods do and what arguments they take, but I'm hoping to find out how they work.
