* 3. The signature of the delegate must match the signature of the function the delegate points to, otherwise you will get a compiler error.
* this is why delegate is called as type safe function pointers.
* 4. It is similar to class, you can create an instance of it, and when you do so. You pass in the function name as paramerter to delegate constructor.
* and it is to this function the delegate will point to.
*
* TIPS :: To remember delegate syntax:
* It looks very similar to function syntax with delegate keyword with it.
