/*
Inline 01

If function is called following activities carried out
- Jumping to the function
- Saving the register
-    Pushing the argument into stack.
- Return to the calling function

These activities can be avoided if we use inline....

Inline functin cannot work in following situation
- For function returning a value using If, Loop, Switch, goto
- For function not returning value and return statements are exist
- If function contains static variable
- if inline function is recursion

#include <iostream.h>
#include <iomanip.h>
#include <conio.h>


class Digits
{
private:
long int n;
public:
Digits(long int pass)
{
n = pass;
}
inline int sum(long int m, int add);
void display(long int);
~Digits()
{
cout << "Destructor is called " << endl;
}
};

//=================================================
// Inline member function
//=================================================
int inline Digits :: sum(long int m, int add)
{
return(add + m%10);
}

//=================================================
//  Display member function
//=================================================
void Digits :: display(long int m)
{
cout << "Sum is : " << m << endl;
}

//=================================================
// Main Function
//=================================================
void main()
{
clrscr();
long int n;
int temp = 0;

cout << "Enter the long int no ";
cin >> n;

Digits d1(n);

while(n>0 || temp>9)
{
temp = d1.sum(n,temp);
n = n / 10;
d1.display(temp);

if(n==0 && temp > 9)
{
n = temp;
temp = 0;
}
} //while

getch();
} //void main
