In this exercise, you'll write a function named quadruple to compute the quadruple of a number. The quadruple of a number is itself times four: Your function should take one parameter and return the quadrupled value. Your function should return the quadruple of the number, not print It$.$ Instead, you'll need to store the value returned by the function call into a variable.

For example, the following code should put the value $12$ in $x.$

$x=$ quadruple$(3)$

Call your quadrupie function at least two times with dlfferent numbers, and print the results each time to check your function's output.
