Exponents with while

Instructions

Here is a bit of code that you can use to calculate exponents, with a being the base and b the exponent:

a^b

Part 1

Given that b is an integer number, write a bit of code with a while() loop to calculate the exponent! Do not use the exponent/hat ^ and using only the multiplication * operator!

Part 2

Make a function from the code you wrote earlier with the following parameters:

name	`Exp()`
params	`base`: the base of the expression
	`ex` : the exponent
return	The result.
