some times i see that functions are defined as below:

read_dir(dir)
char    *dir;   
{
        DIR * dirp;
        struct dirent *d;

        /* open directory */
        dirp = opendir(dir);
  ......... so  on

here what is the importance of the statement

char    *dir;

what is the intension behind declaring the pointer soon after the function name and then starting the function body.

I'm looking at a member function int funct(int x) const; And I'm wondering if static int funct(int x); would be better. If a member function doesn't use any of the member variables should it be static. Are there any things that would discourage this? >>> More

I was expecting to replace all Wide functions, e.g. WideUpperCase, with their equivalent, e.g. UpperCase, but they do not work the same way. For example, WideUpperCase… >>> More

I know this question might be frowned upon, but actionscript is a dynamic language similar to javascript and in javascript I can take an object from a library written by someone else and dynamically (at runtime) add/remove/modify functions, properties, prototypes etc. this is kind of like dynamically… >>> More

Sorry for long winded title, this makes a lot more sense with an example. Suppose we have a class A: class A { public: void someFunction(); void someOtherFunction(); }; And another class that privately inherits from A. However, we re-declare one of the inherited functions as… >>> More
