This highly interactive course introduces you to fundamental programming concepts in PHP, one of the most popular languages in the world. It begins with a simple Hello world program and proceeds on to cover common concepts such as Conditional Statements, Loop Statements, and Logic in PHP. 

It then reflects upon the idea of Functions and Arrays, as well as the power they give to the programmer to write better code. 

Finally, it dives deeper in order to teach about advanced concepts such as Classes, Inheritance and Exception Handling in PHP. By the time you're done, you'll have a good grip on the basics of PHP, and will be ready to study advanced concepts.

## Problem Statement

Write a code which will take: 
*  Two variables named `num1` and `num2`   
*  a `string` type variable called `Operator` which will be passed as **input** to our switch statement.
* The `Operator` variable can be passed the following:                       

  * `+`,`-`,`*` and `/` 
* Use `switch` statements to compute: 
  * **addition**, 
  * **subtraction**, 
  * **multiplication** 
  * **division** 

> **Note:** For the default case, simply print the statement `echo "Wrong operator";`.

## Sample Input
```
num1 = 5.5
num2 = 6.5
Operator = '+'
```

## Sample Output

```
Output = 12
```
