Re: Too many member functions?

My project grows large when I put too many member functions into one
class. The header file and source code file will have approximately
50,000 lines when one class contains thousand member functions. Is it
normal how C++ Compiler can compile large class without any problem?
Didn't C++ Compiler have rules to limit the number of member
functions?
The is a QOI issue, not a standards issue.
One big object has complex operations how member variables and member
functions can be manipulated according to my design. I put almost
4,000 member functions inside one class. The class with 4,000 member
functions is compiled without any problems and it runs very well.

And there are programs with 10000 lines of spaghetti code running fine
as well, but running well is not the only criterion for a good
program. Comprehensibility, maintainability, fragility, testability,
etc. also need to be considered. Encapsulation and data hiding are
tools we use to manage complexity. You have a chainsaw available; why
use the hacksaw? See any book on OO programming and/or these FAQs:

These thousand member functions are like one big vtable pointer.
One big member function pointer array can be used to access all
thousand functions like this p_mfunc[xx][xx][xx](); This is neat when
I allow to group thousands functions into main functions, sub-
functions, and sub-sub-functions.
There are other ways to do this than a morbidly obese interface.
