Slip 9 - A) Write a PHP program to create a Class Calculator which will accept two values from user and pass as an argument through parameterized constructor and do the following task: a) Add b) Subtract c) Multiply them together or divide them on request.

 Solution:

<?php

class Calculate

{

public $a;

public $b;

function __construct($a,$b){

$this->a=$a;

$this->b=$b;

}

public function add()

         {

          $c=$this->a+$this->b;

echo"Addition = $c<br>";

         }

public function subtract()

         {

          $c=$this->a-$this->b;

echo"Subtract = $c<br>";

         }

public function multiply()

         {

          $c=$this->a*$this->b;

echo"Multiplication = $c<br>";

         }

public function div()

         {

          $c=$this->a/$this->b;

echo"Division = $c";

         } }

//$x=$_GET['a'];

//$y=$_GET['b'];

$calc=new Calculate(4,3);

$calc->add();

$calc->subtract();

$calc->multiply();

$calc->div();?>
