need help creating two source files..

ok say heres my code in once source file..

Code:

#include <sstream> 
#include <fstream>
#include <iostream>
#include <string>
#include "stdlib.h"
#define SIZE 50 // size of the array

using namespace std;

class store // defines a class with variables
{
      public:
             int custnum;
             string product;
             int quantity;
             string month;
             string day;
             string year;
             int tmpcustnum;
             int tmpquantity;
             string tmpmonth;
             string tmpday;
             string tmpyear;
             bool isfirsttime;
};
store STORE1[SIZE]; // creates a class


void menu()
{
.
.
}

void period(int num_line, string productname, string month1, string day1, string year1, string month2, string day2, string year2)
{
.
.
}

int main()
{
    menu(); // calls menu function
    system("PAUSE");
    return 0;   
}

what would i put in the header file.. the menu and period functions use the class..

this is my header file

Code:

#ifndef BANK_H  
#define BANK_H
#define SIZE 50

class store // defines a class with variables
{
      public:
             int custnum;
             string product;
             int quantity;
             string month;
             string day;
             string year;
             int tmpcustnum;
             int tmpquantity;
             string tmpmonth;
             string tmpday;
             string tmpyear;
             bool isfirsttime;
      
};
store STORE1[SIZE]; // creates a class
void menu();
#endif

i included my header file and when i try to compile main.cpp

Code:

#include <sstream> 
#include <fstream>
#include <iostream>
#include <string>
#include "bank.h"

int main()
{
    menu(); // calls menu function
    system("PAUSE");
    return 0;   
}

it gives me this error 18 K:\...\bank.h `string' does not name a type


also how would i do a makefile?

any1 plz!! my program is due tomorrow

Your problem I think is that bank.h dosen't include the 'string' header file where the string class is defined.

still gives me same error

You also need to put using namespace std; in the header file or precede the string type with std::.

i revised my header file but now it says menu is undefined..

Code:

#define SIZE 50
#include <sstream> 
#include <fstream>
#include <iostream>
#include <string>
using namespace std;
class store // defines a class with variables
{
      public:
             int custnum;
             string product;
             int quantity;
             string month;
             string day;
             string year;
             int tmpcustnum;
             int tmpquantity;
             string tmpmonth;
             string tmpday;
             string tmpyear;
             bool isfirsttime;

};
store STORE1[SIZE]; // creates a class

void menu();

Where is the menu function code. It should be in main.cpp.

the menu function is in my other c++ file - i put menu() in main now its giving me errors that my other functions are undeclared since menu calls other functions

Separate all the method definitions into one or more source files (.cpp) however you think they should go. Then, in each source file, look for each function defined or used and each class used, and include the header that declares that function or class.

Then make sure to compile all the source files and link them together and it should work.

Does that mean it works, or are there still errors? Give the full, exact error messages if there are errors.

it works i discarded the header file and just includded functions.cpp in main.cpp ... thanks

uhh ok but there shouldn't be a need to do that. Just remember every cpp file that uses a function must include the header where that function is prototyped. The cpp that defines that function must also include the header file.

Also, if their are multiple source files, you may need to compile them separately and then link them together as the last step.
