Static Members Both Data And Function

Program To Illustrate The Concept Of Static Members :

#include<iostream>
using namespace std;
class datatype
{
    int a;
    static int count;
    public:
        datatype()
        {
            a=++count;
        }
        void show()
        {
            cout<<"\nValue of Variable is "<<a;
        }
        static void showcount()
        {
            cout<<"\nNo of Objects cretaed "<<count;
        }
};
int datatype::count;

main()
{
    datatype a,b,c;
    a.show();
    b.show();
    c.show();
    datatype::showcount();
}

PROGRAM TO ILLUSTRATE THE CONCEPT OF INLINE FUNCTION WITHIN THE CLASS

PROGRAM TO ILLUSTRATE THE CONCEPT OF INLINE FUNCTION WITHIN THE CLASS.

#include <iostream>
using namespace std;
class square
{
public:
int num;

void getdata()
{
cout<<"Enter the Number: ";
cin>>num;
}

int sq();
};

inline int square::sq()
{
return (num*num);
}

int main()
{
square s;
s.getdata();
cout<<"\nSquare of Number is "<<s.sq();
}

PROGRAM TO ILLUSTRATE THE CONCEPT OF CLASS AND OBJECT:
// program to illustrate the concept of classes ans=d objects
#include<iostream>
using namespace std;
class student
{
private:
int rollno;
float marks;
char name[20];
public:
void getdata()
{
cout<<"ENTER NAME ";
cin>>name;
cout<<"ENTER ROLL NO";
cin>>rollno;
cout<<"ENTER MARKS";
cin>>marks;
}
void print()
{
cout<<"YOU ENTERED";
cout<<"\nNAME: "<<name;
cout<<"\nROLL NO: "<<rollno;
cout<<"\nMARKS: "<<marks;
}
};
main()
{
student s;
s.getdata();
s.print();
}
