Basic banking program with header files

[hybrid87]

Hi all,

For my programming class I must create a simple banking program with a DB in Array. I've got all that working great. But I'm stuck at one of the points in the task - each function must be in a separate header file.

Can someone help me move one of the functions to a header? :)

Here what I've got so far:

#include <iostream>
using namespace std;
 
struct clientData   
{
   int accNum;  
   char Sur[15];    
   char Name[10];   
   float balance;  
   void operator=(clientData * c)
   {
        accNum = c->accNum;
        for(int i=0;i<15;i++)
            Sur[i] = c->Sur[i];
        for(int i=0;i<15;i++)
            Name[i] = c->Name[i];
        balance = c->balance;
   }
};
 
class base
{
    clientData * cl;
    int maxSize;
    int count;
public:
    base()
    {
        maxSize = 100;
        cl = new clientData[maxSize];
        count = 0;
    }
    ~base()
    {
        delete cl;
    }
    void add();
    void print();
    void del();
    void find();
    void setBalance();
    void printDoubt();
    void printCount();
    char PrintMenu();
};

void base::printCount()
{
//Function to print out number of clients
}
void base::add() //To add a new client
{
    cout<<"Input Surname:";
    cin>>cl[count].Sur;
    cout<<"Input Name:";
    cin>>cl[count].Name;
    cout<<"Input Balance:";
    cin>>cl[count].balance;
    cl[count].accNum = count;
    count++;
}
void base::print()
{
//Function to print out all client data
}

void base::del()
{
//Function to delete client
}

void base::setBalance()
{
//Function to change balance
}

void base::find()
{
//Function to find client based on accNum
}

void base::printDebt()
{
//Function to print clients with debt
}

char base::PrintMenu()
{
    char a;
 
        cout<<"1: Add client"<<endl;
        cout<<"2: Deelete client"<<endl;
        cout<<"3: Print all clients"<<endl;
        cout<<"4: Find client"<<endl;
        cout<<"5: Edit balance"<<endl;
        cout<<"6: Print client with debt"<<endl;
        cout<<"7: Print count of clients"<<endl;
        cout<<"q: Quit"<<endl;
        cin>>a;
        return a;
}

int main()
{
    base * b = new base;
    while(true)
    {
        switch(b->PrintMenu())
            {
                case '1':b->add(); break;
                case '2':b->del(); break;
                case '3':b->print(); break;
                case '4':b->find(); break;
                case '5':b->setBalance(); break;
                case '6':b->printDoubt(); break;
                case '7':b->printCount(); break;
                case 'q':exit(1); break;
                default: cout<<"Incorrect letter"; break;
            }
    }
}

Here is what I try to do it:
1: Make add.h and add.cpp files to move the function to add a client
2: Add #include "add.h" to the main file
3: Move this to add.cpp

#include <iostream>
using namespace std;

void base::add()
{
    cout<<"Input Surname:";
    cin>>cl[count].Sur;
    cout<<"Input Name:";
    cin>>cl[count].Name;
    cout<<"Input Balance:";
    cin>>cl[count].balance;
    cl[count].accNum = count;
    count++;
}

4: Move this to add.h

#include <iostream>
using namespace std;

void base::add();

When I run the compiler it says

[Error]'base' has not been declaired

(pointing to add.h file). So the add.h file doesn't see the DB from the main file.

Any tips or ideas?

[Bdanielz]

You have at least have typo.


printDoubt()

or

printDebt()

Also are you sure you mean your teacher wants a separate header file for each function? or a separate header file for each class?

[hybrid87]

Here is the whole task (translated from Latvian, since the class is in Latvian)

Based on this structure:
struct clientData // client Data
{
int accNum; // account number
char Sur[15]; // surname
char Name[10]; // name
float balance; // balance
};

Create database in form of an array. There must be a main menu with such entries:
* Add entry
* Delete entry
* Print out all entries
* Find an entry (by account number)
* Change account balance (find account by number and input a value to add to the balance)
* Show all clients with debt
* Count entries
* Exit

Additionaly the program should have this:
* Account number must be the index value
* Array size - 100 entries
* Each operation must be in a separate funktion
* Each function must be in a separate header file
* After each operation the user has to be taken back to the main menu.

More or less I have everything except that each function must be in a separate file.

[Error]'base' has not been declaired

You need to include the file where the class base is declared.

[hybrid87]

That's the main file.
How to include the main file in the header file?
#include "main.cpp" ???

[TarikNeaj]

You cant do that. You should probably move the class to a new header, and include that header in main.

[xenoviaquarta]

move your class base to your add.h

[hybrid87]

OK I've put clientData and class base in base.cpp and base.h. Also moved add function to add.h and add.cpp.

Here is what I've got now:

main.cpp

#include <iostream>
#include "base.h"
#include "add.h"
using namespace std;

void base::printCount()
{
//Function to print out number of clients
}

void base::print()
{
//Function to print out all client data
}

void base::del()
{
//Function to delete client
}

void base::setBalance()
{
//Function to change balance
}

void base::find()
{
//Function to find client based on accNum
}

void base::printDebt()
{
//Function to print clients with debt
}

char base::PrintMenu()
{
    char a;
 
        cout<<"1: Add client"<<endl;
        cout<<"2: Deelete client"<<endl;
        cout<<"3: Print all clients"<<endl;
        cout<<"4: Find client"<<endl;
        cout<<"5: Edit balance"<<endl;
        cout<<"6: Print client with debt"<<endl;
        cout<<"7: Print count of clients"<<endl;
        cout<<"q: Quit"<<endl;
        cin>>a;
        return a;
}

int main()
{
    base * b = new base;
    while(true)
    {
        switch(b->PrintMenu())
            {
                case '1':b->add(); break;
                case '2':b->del(); break;
                case '3':b->print(); break;
                case '4':b->find(); break;
                case '5':b->setBalance(); break;
                case '6':b->printDoubt(); break;
                case '7':b->printCount(); break;
                case 'q':exit(1); break;
                default: cout<<"Incorrect letter"; break;
            }
    }
}

base.cpp

#include "base.h"
struct clientData   
{
   int accNum;  
   char Sur[15];    
   char Name[10];   
   float balance;  
   void operator=(clientData * c)
   {
        accNum = c->accNum;
        for(int i=0;i<15;i++)
            Sur[i] = c->Sur[i];
        for(int i=0;i<15;i++)
            Name[i] = c->Name[i];
        balance = c->balance;
   }
};

class base
{
    clientData * cl;
    int maxSize;
    int count;
public:
    base()
    {
        maxSize = 100;
        cl = new clientData[maxSize];
        count = 0;
    }
    ~base()
    {
        delete cl;
    }
    void add(); //Add client
    void print(); //Show all clients
    void del(); //Delete client
    void find(); //Find cliete
    void setBalance(); //Change balance
    void printDebt(); //Show clients with debt
    void printCount(); //Count clients
    char PrintMenu(); //Show menu
};

base.h

#ifndef BASE_H
#define BASE_H
struct clientData   
{
   int accNum;  
   char Sur[15];    
   char Name[10];   
   float balance;  
   void operator=(clientData * c)
   {
        accNum = c->accNum;
        for(int i=0;i<15;i++)
            Sur[i] = c->Sur[i];
        for(int i=0;i<15;i++)
            Name[i] = c->Name[i];
        balance = c->balance;
   }
};

class base

    clientData * cl;
    int maxSize;
    int count;

#endif 

add.cpp

#include <iostream>
#include "base.h"
using namespace std;

void base::add()
{
    cout<<"Input Surname:";
    cin>>cl[count].Sur;
    cout<<"Input Name:";
    cin>>cl[count].Name;
    cout<<"Input Balance:";
    cin>>cl[count].balance;
    cl[count].accNum = count;
    count++;
};

add.h

#include <iostream>
#include "base.h"
using namespace std;

void base::add();

Now when compiling I get this error:

[Error] declaration of 'void base::add()' outside of class is not definition [-fpermissive]

(Points to add.h line 5)

[hybrid87]

Thank you everyone for helping :) Solved it myself.

main.cpp

#include <iostream>
#include "base.h"
#include "add.h"
#include "printCount.h"
#include "print.h"
#include "delete.h"
#include "setBalance.h"
#include "find.h"
#include "printDebt.h"
#include "menu.h"
using namespace std;

int main()
{
    base * b = new base;
    while(true)
    {
        switch(b->PrintMenu())
            {
                case '1':b->add(); break;
                case '2':b->del(); break;
                case '3':b->print(); break;
                case '4':b->find(); break;
                case '5':b->setBalance(); break;
                case '6':b->printDebt(); break;
                case '7':b->printCount(); break;
                case 'q':exit(1); break;
                default: cout<<"Incorrect letter"; break;
            }
    }
}

base.h

#ifndef BASE_H
#define BASE_H
struct clientData   
{
   int accNum;  
   char Sur[15];    
   char Name[10];   
   float balance;  
   void operator=(clientData * c)
   {
        accNum = c->accNum;
        for(int i=0;i<15;i++)
            Sur[i] = c->Sur[i];
        for(int i=0;i<15;i++)
            Name[i] = c->Name[i];
        balance = c->balance;
   }
};

class base
{
    clientData * cl;
    int maxSize;
    int count;
public:
    base()
    {
        maxSize = 100;
        cl = new clientData[maxSize];
        count = 0;
    }
    ~base()
    {
        delete cl;
    }
    void add(); //Add client
    void print(); //Show all clients
    void del(); //Delete client
    void find(); //Find cliete
    void setBalance(); //Change balance
    void printDebt(); //Show clients with debt
    void printCount(); //Count clients
    char PrintMenu(); //Show menu
};
#endif 

as an example - add.h

#include <iostream>
#include "base.h"
using namespace std;

void base::add()
{
    cout<<"Input Surname:";
    cin>>cl[count].Sur;
    cout<<"Input Name:";
    cin>>cl[count].Name;
    cout<<"Input Balance:";
    cin>>cl[count].balance;
    cl[count].accNum = count;
    count++;
};

Works like a charm :)
