Then why did you promise you could do it?

To play the game you will have to give your player commands like,

go north
eat cow
kill sheep

This will be a mix of adventure and RPG

That part was clear to me. Still I'm curious how your game is designed (NOT how it's coded). What classes are you using, how do they relate? And surely you're not planning to hardcode all the rooms? Your code gives no clue about this (there's not much there anyway).

You should look into XML! You could specify your rooms in a rather simple way:

<room type="normal" id="123">
 * <name>The Ultradark and dank Dungeon</name>
 * <exit>
 * * * <dir>North</dir>
 * * * <desc>The sturdy wooden door</desc>
 * </exit>
 * * *<exit>
 * * * <dir>West</dir>
 * * * <desc>A chain hanging from the ceiling</desc>
 * </exit>
 * <desc>The walls in this dark and dank dungeon are covered in what seem to be
 * * * * * * *troll excrements. Some are still warm and extremely smelly. Bit of toilet
 * * * * * * *paper can be seen between the goo. </desc>
</room> *

Something like this. Off course, i'd give some more thought to a reallly decent DTD You can use any XML-lib for C++ (I'm into Java myself, so I don't know any...).

@ Punch
I thought i could do it LOL

@ Reup
Wait and see i've only just got to work on the game it's self.

A question for any one who can program C++

How will i save the players stats like, attack = 1, defence = 5
as fwrite and fread only accept char and strings ?

[NrmMyth]

For anything.

Syntax:

 #include <stdio.h>
 *int fwrite( const void *buffer, size_t size, size_t count, FILE *stream );

The fwrite() function writes, from the array buffer, count objects of size size to stream. The return value is the number of objects written.

[chickenman]

hmmmm i have tryed a number of things but i still can't get it to work.

28 C:\SYS\Desktop\cpp\int-save-test\main.cpp invalid conversion from `int' to `const void*'

#include <iostream>
#include <fstream>
using namespace std;

int main()
{
int age = 15;
int number = 22;
char Fname[12]; //for filename
cout<<"Enter file to save to: ";

cin.getline(Fname,12); //get data
cout<< endl;

//Open file
FILE *file;
file = fopen (Fname,"w");

fwrite (age,1,sizeof(age),file);
fwrite (number,2,sizeof(number),file);

cin.get();
return 0;
}

[Data]

uhm try &age instead of age
and &number instead of number

[mik]

#include <iostream>
#include <fstream>
using namespace std;

int main()
{
int age = 15;
int number = 22;
char Fname[12]; //for filename
cout<<"Enter file to save to: ";

cin.getline(Fname,12); //get data
cout<< endl;

//Open file
FILE *file;
file = fopen (Fname,"w");

char buffer[2];
_itoa(age, buffer, 10); //convert int to char
fwrite (buffer,sizeof(buffer), 1, file);
_itoa(number, buffer, 10);
fwrite (buffer,sizeof(buffer), 1, file);

cin.get();
fclose(file);
return 0;
}

It is work.

[chickenman]

Well it works but I don't understand the
_itoa(number, buffer, 10);

also how do I load the saved data into the correct integers?

:eeeeeh:

[mik]

So, I don't think that it's a good idea to use "fwrite" here but if you want...

_itoa - convert an integer to a string (see MSDN).
Code for save and load:

#include <iostream>
#include <fstream>
using namespace std;

int main()
{ 
int age = 15;
int number = 22;
char Fname[12]; //for filename 
cout<<"Enter file to save to: ";

cin.getline(Fname,12); //get data
cout<< endl;

//Open file
FILE *file;
if ((file = fopen (Fname,"w")) != NULL)
{
	char buffer[2];
	_itoa(age, buffer, 10); //convert int to char
	fwrite (buffer,sizeof(char), 2, file);
	_itoa(number, buffer, 10);
	fwrite (buffer,sizeof(char), 2, file);
	fclose(file);
}
else cout<<"Error opening the file";

if ((file = fopen (Fname,"r+t")) != NULL)
{
	char ch_age[2], ch_number[2];
	fread(ch_age, sizeof(char), 2, file);
	fread(ch_number, sizeof(char), 2, file);
	fclose(file);

	age = atoi(ch_age); //convert char to int
	number = atoi(ch_number);
	cout<<"Age = "<<age<<" Number = "<<number;
}
else cout<<"Error opening the file";

cin.get();
return 0;
}

Or as you really seem to wanting to learn C++
use ifstream and ofstream class.
then you can just output and load stuff like you do with cin/cout
