Hi i have this code below i am encountering that my int a,b; got error because they are delcare in private. but the code turn out fine if i delcare them in public.
is there anyway i can make them remain in private. i think need to use reference or wad. can anyone help me one this?
Code:
#include <iostream>
#include <string>
#include <stdlib.h>
#include <string.h>
using namespace std;
class Account
{
//declaration of friend functions
friend ostream& operator<<(ostream&,const Account&);
friend istream& operator>>(istream&,Account&);
friend Account operator +(const Account&,int);
//friend Account Account::operator+(double r)
//friend Account operator +(int,const Account&);
//declaration of public members
public :
Account();
Account(int a1,int b1);
Account operator +(const Account&)const;
//declaration of private members
private:
int a,b;
};
//constructor for matrix class
Account::Account()
{
a=0;
b=0;
}
Account::Account(int a1,int b1)
{
a=a1;
b=b1;
}
//overloading stream extraction operator
ostream& operator << (ostream &out,const Account &ac)
{
//out << ac.a << "." << ac.b << endl;
out << ac.a << "."<<ac.b << endl;
return out;
}//end of function
//overloading stream insertion operator
istream& operator >>(istream &in,Account &ac)
{
string a,b,s;
fflush(stdin);
getline(in,s);
a = s.substr(0);
b = s.substr(0);
ac.a = atoi(a.c_str());
string::size_type nDecimalPosition = s.find('.');
if (nDecimalPosition != string::npos)
ac.b = atoi(s.c_str() + nDecimalPosition + 1);
return in;
}
Account operator +(const Account &rhs,double i)
{
Account temp;
//temp.a = rhs.a+i;
//temp.b = rhs.b+i;
double temprhs = (double)rhs.a + (double)rhs.b / 100;
double result = 0.0;
cout << "temprhs " << temprhs << endl;
cout << "i " << i << endl;
result=temprhs+i;
temp.a = (int)result;
temp.b = (int)((result - (int)result) * 100);
return temp;
}//end of function
int main()
{
Account A, B, C;
cout << "Enter first account balance, format xx.yy: ";
cin >> A;
cout << "Enter second account balance, format xx.yy: ";
cin >> B;
C = A + 20.70;
cout << "Addition A + 20.70 = " << C << endl;

Hi Gurus,
I know this sounds weird, We have encountered many incidents where some directories on several Solaris 10 boxes, will be converted to files with the same size. for example the file below :

zipios_referencecount
zipios::ReferenceCount(3) Library Functions Manual zipios::ReferenceCount(3)NAME
zipios::ReferenceCount -
ReferenceCount is useful to ensure proper handling of the reference count for (objects of) classes handled through a SimpleSmartPointer.
SYNOPSIS
#include <simplesmartptr.h>
Public Member Functions
ReferenceCount ()
Constructor intializes count to zero.
ReferenceCount (const ReferenceCount &src)
Copy-constructor intializes count to zero.
const ReferenceCount & operator= (const ReferenceCount &src)
The assignment operator doesn't copy the reference count, it leaves it unchanged.
Friends
class SimpleSmartPointer< Type >
SimpleSmartPointer needs to be a friend to invoke the private ref() and unref() methods.
class SimpleSmartPointer< const Type >
class FileEntry
Type also needs to be a friend to invoke the private ref() and unref() methods, in case Type doesn't want to inherit ReferenceCount and
thus needs to invoke ref() and unref() through forwarding member functions.
class Bogus
Detailed Description
template<class Type>class zipios::ReferenceCount< Type >
ReferenceCount is useful to ensure proper handling of the reference count for (objects of) classes handled through a SimpleSmartPointer.
Subclassing ReferenceCount is all a class needs to become ready for being handled by SimpleSmartPointer. Another way is to add a
ReferenceCount member variable to a class and write two methods 'void ref() const' and 'unsigned int unref() const' that invoke the same
methods in the ReferenceCount variable.
