Static member functions.

Write a C++ program to classes with static member functions.

Algorithm:

Step 1: Create a class as the item.

Step 2: Declare the data members.

Step 3: Declare the member functions.

Step 4: In the main, create an object for the class.

Step 5: Call the function.

Step 6: Get the output.

Step 7: Stop the program.

Program Code:

#include<iostream.h>

#include<conio.h>

class item

{

static int count;

int num;

public:

void getdata(int a)

{

num=a;

count++;

cout<<"Number : "<<num<<endl;

}

void showcount()

{

cout<<"count : ";

cout<<count<<”\n”;

}

};

int item::count;

int main()

{

item a,b,c;

clrscr();

a.showcount();

b.showcount();

c.showcount();

a.getdata(20);

b.getdata(30);

c.getdata(40);

a.showcount();

b.showcount();

c.showcount();

getch();

}

Output:

count : 0

count : 0

count : 0

Number : 20

Number : 30

Number : 40

count : 3

count : 3

count : 3
