Creating object for a class in object oriented programming

consider the example


#include%26lt;iostream.h%26gt;


#include%26lt;conio.h%26gt;





class employee


{


char name[20];


int num;


float da,bs,it,net;


public:employee(){}


void get()


{


cout%26lt;%26lt;';Enter the name:';;


cin%26gt;%26gt;name;


cout%26lt;%26lt;';Enter register number:';;


cin%26gt;%26gt;num;


cout%26lt;%26lt;';Enter basic salary:';;


cin%26gt;%26gt;bs;


}


void netsalary()


{


da=0.52*bs;


it=0.3*bs;


net=da+bs-it;


}


void disp()


{


cout%26lt;%26lt;name%26lt;%26lt;';\t';%26lt;%26lt;num%26lt;%26lt;';\t';%26lt;%26lt;bs%26lt;%26lt;';\t\t';%26lt;鈥?br>

}


};








void main()


{


employee e[10];


clrscr();


cout%26lt;%26lt;';Enter the number of employees:';;


int n;


cin%26gt;%26gt;n;


cout%26lt;%26lt;';Enter employee details\n';;


for(int i=0;i%26lt;n;i++)


{


cout%26lt;%26lt;';Enter details of employee ';%26lt;%26lt;i+1%26lt;%26lt;';\n';;


e[i].get();


e[i].netsalary();


}


cout%26lt;%26lt;';EMPLOYEE DETAILS ARE\n';;


cout%26lt;%26lt;';\nNAME\tREG NO.\tBASIC SALARY\tNET SALARY\n';;


for(i=0;i%26lt;n;i++)


{


e[i].disp();


}


getch();


}





this is creating object for a class in object oriented programming. it is c++ programming.Creating object for a class in object oriented programming
any class is collection of data members(variables) and methods(functions)





to define an object first define a class





syntax





class class_name





{


public static void main(String args[])


{


class_name object_name= new class_name();


}


}





example in java:


class fruits


{


public static void main(String args[])





{


fruits mango= new fruits();


fruits orange = new fruits();


fruits apple = new fruits();





}


}











Creating object for a class in object oriented programming
taken by example


class student


{


private:


int a;


public:


void getdata();


}


void main()


{


student obj; //declaration of object of a class named student


:


:


:


}
In PHP:








// Class declaration


class Foo


{


public $bar;


function __construct($bar)


{


$this-%26gt;bar = $bar;


}


}





//Object instantiation





$bar = new Foo('foo_bar');
in c++





class class name


//body


}





void main()


{


class name obj;


}








this is just a rough idea in c++ to declare object
