Classes

Im pretty sure, this has allready been answered, but I used the search and i couldn't find anything, so...
Im new to c++ but not new in programming.

I need several procedures (probably around 50), that I would like to group in the same classes. For example, file related procedures in one class, math related in the other... and have one class per file.
The problem is, I have no idea, how to do that.

At the moment, I have each class in its own cpp file, each cpp file has a header file and a file with main function.

This is bascly how things look like:

files.h

Code:

#ifndef FILES_H
#define FILES_H
class files{
	public:
		static bool exists(char *path[]);
};
#endif

files.cpp

Code:

#include "files.h"

static bool exists(char *path[]){
	//code
	return false;
}

main.cpp

Code:

#include <stdio.h>
#include "files.h"

int main(int argc, char *argv[])
{
	printf("\n");
	//were is where i'd like to use the function
	return 0;
}

That looks good, but writing a class function is a little different:

Code:

#include "files.h"

bool files::exists(char *path[]){
	//code
	return false;
}

you create an "instance" of the class to use
basicly your main function would look like this

Code:

#include <iostream>
#include "files.h"

int main(int argc, char *argv[])
{
   files* MyFiles = new files;
   std::cout << std::endl;
   MyFiles->exists("your path");
   delete MyFiles;
   return 0;
}

or something to that effect. That is if I understood your question correctly.

Thanks for the quick reply.

I changed the class definition as you suggested Noir.
Raigne, you understood correctly, but that procedure is static, so i wouldnt need to create the object (or am I missing something and things are different in c++?).

However, I tried your code and got this error:
main.cpp:9: error: no matching function for call to ‘files::exists(const char [10])’
files.h:5: note: candidates are: static bool files::exists(char**)

Do you really need to use a pointer? This works better:

Code:

#include <iostream>
#include "files.h"


int main( int argc, char *argv[] ) {
   std::cout << std::boolalpha << MyFiles::exists( argv + 1 ) << '\n';
}

why not pass the
const char* path?
Why do you need this pointer to array thing?

vart, thats kinda not the point right now...

How is so?
Last question was

However, I tried your code and got this error:
main.cpp:9: error: no matching function for call to ‘files::exists(const char [10])’
files.h:5: note: candidates are: static bool files::exists(char**)

exactly about this...

Sorry, didn't know that...
So I replace char *argv[] with const char* path?
If so, this is what i get now: undefined reference to `files::exists(char const*)'

Did you fix it everywhere?

I'm also not quite sure why you need classes here. If you want to decorate the names why not put related things in a namespace instead?

Yes, i fixed it everywhere.
The classes are... a matter of personal preference

The classes are... a matter of personal preference

If those static member functions are not going to access any static member variables, then they really should be free functions instead, possibly in a namespace of your choice.

The above code is pretty much just an example.
I will need classes because i'll need objects, so I should really get this working.
