Functions in class and class variables.

The class doesn't sees the function "place();" in the main.cpp and the int x and int y is also not recognized when using it in the functions owned by the class:

Code:

#ifndef ORGAN_H
#define ORGAN_H

class Organ
{
public:
    int x;
    int y;
 
    void kill(int a,int b);
    void it_lives(int prop);
    void SetCoord(int x, int y);

};

#endif // ORGAN_H

Code:

#include "organ.h"

void SetCoord(int x, int y)
{
    place(x,y,"@");//ERROR: Undeclared
}
void kill(int a,int b)
{
    x=a;//ERROR: x and y undefined
    y=b;
    place(x,y," ");
}
void it_lives(int prop)
{
    if(prop==0)
    {
        kill(x,y);
    }
}

place(); is defined in the main.cpp file. The header file is defined in the main.cpp.

void SetCoord(int x, int y)
{
place(x,y,"@");//ERROR: Undeclared
}
You need the class name as well

Code:

void Organ::SetCoord(int x, int y)
{
    place(x,y,"@");//ERROR: Undeclared
}

> The class doesn't sees the function "place();"
Then prototype it in a header file, and include that header file in organ.cpp

I made a new header, "functions.h", but so, the functions were also needed by the main.cpp and I included it also to the main.cpp, now I get:
The Build log:
.objs\main.o:main.cpp.text+0x100): multiple definition of `gotoxy(int, int)'
.objs\organ.organ.cpp.text+0x100): first defined here
.objs\main.o:main.cpp.text+0x13e): multiple definition of `place(int, int, std::string)'
.objs\organ.organ.cpp.text+0x13e): first defined here
The Build message:
#warning: This file includes at least one deprecated or antiquated header. Line 32.
In line 32 there is just a struct definition, no problem there.

I don't have any duplications of these functions, what's wrong?
Thanks.

That's what happens when you put code inside header files.

My guess, your functions.h has

Code:

void gotoxy ( int x, int y ) {
  // something from the FAQ?
}

Rather than having
void gotoxy ( int x, int y );

And in functions.cpp

Code:

#include "functions.h"
void gotoxy ( int x, int y ) {
  // something from the FAQ?
}

> #warning: This file includes at least one deprecated or antiquated header. Line 32.
You have something like
#include <iostream.h>

You should remove the .h from all your C++ header files, like this
#include <iostream>

Also, C headers included in C++ programs were written as
#include <stdlib.h>
Which would now be
#include <cstdlib> // prepend c, and lose the .h

Finally, after all the includes, add
using namespace std;

Eg.

Code:

#include <iostream>
#include <cstdlib>
using namespace std;
// rest of C++ code

Ok, thanks .
I added the whole function to the functions.h file (I didn't know what a prototype was), and the deprecation was string.h and iostream.h.
