hii,

i wrote this prog

//header file

#include <string>

using namespace std;

class expenditure

{

public: //public member function

void set(string, int,int,int);

void get(string&, int&,int&,int&) const;

static int getCount();

static int gettotalexpenditure( );

void print() const;

expenditure (string = "Al-Mullah", int= 800, int = 2400, int= 1200);

~ expenditure ();

static double averageExpenditure();

private: // private member function

string name;

int utilities ;

int food;

int personal;

int subtotal;

static int count;

static int totalexpenditure ;

};

// ExpenditureImp.cpp

#include<iostream>

#include<string>

#include"Ex.h"

using namespace std;

int expenditure :: count=0;

int expenditure ::totalexpenditure=0;

void expenditure::set(string N , int u , int f, int p) // set

function

{

totalexpenditure -=subtotal;

name=N;

utilities = u;

food=f;

personal=p;

subtotal=food+personal+utilities;

totalexpenditure += subtotal;

}

void expenditure::get(string& N , int& u , int& f , int& p)const //

get function

{

f=food;

p=personal;

}

expenditure::expenditure(string N, int u, int f , int p) //

constructor

{

subtotal=0;

set(N,u,f,p);

count++;

}

int expenditure::getCount() // get count

{

return count;

}

int expenditure::gettotalexpenditure( ) //return totalexpenditure

{

return totalexpenditure;

}

expenditure::~expenditure() //distructor

{

count--;

totalexpenditure -= subtotal;

cout << "Number of families is: " << count << " and total Expenditure

is: " << totalexpenditure <<endl;

}

void expenditure:

rint() const // print

{

cout << name << " Expenditure is: " << subtotal << endl;

}

double expenditure::averageExpenditure( )

{

return totalexpenditure/count;

}

#include <iostream>

#include <fstream>

#include <string>

#include "Ex.h"

using namespace std;

const int arraySize = 10;

int main()

{

string N;

int p ,f ,u;

int i;

int numberoffamilies=0;

ifstream inFile("expenditure.txt", ios::in); // reading from file

expenditure A[arraySize]; // array

for(i=0; i<arraySize; i++)

{

A[i].print();

}

cout << "Number of families is: " << expenditure::getCount() << " and

total Expenditure is: " << expenditure::gettotalexpenditure( ) <<

endl;

while(inFile >>N >> u >> f >>p)

A[numberoffamilies++].set(N,u,f,p); // number of families

for(i=0; i<numberoffamilies; i++)

{

A[i].print();

}

cout << "Number of families is: " << expenditure::getCount() << "

and total Expenditure is: " << expenditure::gettotalexpenditure( ) <<

endl;

cout<<" Average families expenditure is:

"<<expenditure::averageExpenditure()<<endl;

return 0;

}

my Question is that when i want to start counting families from the

number 7 instead of 10 what should i do ?do i need to use a new

function or what ??

this is the output i want get

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Al-Mullah expenditure is: 4400

Number of families is: 10 and total expenditure is: 44000

Al-Mullah expenditure is: 5100

Al-Issa expenditure is: 5300

Al-Roome expenditure is: 5457

Al-Shebani expenditure is: 4150

Al-Kurdi expenditure is: 4880

Al-Ali expenditure is: 4720

Al-Walled expenditure is: 3940

Number of families is: 7 and total expenditure is: 33547<<<< here is

my mistake instead of 7 i

Average families expenditure is:

4792.4 am getting 10

Total number of families is: 6 and total expanditure is: 29147

Total number of families is: 5 and total expanditure is: 24747

Total number of families is: 4 and total expanditure is: 20347

Total number of families is: 3 and total expanditure is: 16407

Total number of families is: 2 and total expanditure is: 11687

Total number of families is: 1 and total expanditure is: 6807

Total number of families is: 0 and total expanditure is: 2657

Total number of families is: -1 and total expanditure is: -2800

Total number of families is: -2 and total expanditure is: -8100

Total number of families is: -3 and total expanditure is: -13200
