A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated. $($Submit for $2$ points$).$

$(1)$ Output the user's input.

Enter integer: $4$

You entered: $4$

$(2)$ Extend to output the input squared and cubed. Hint: Compute squared as userNum $*$ userNum. $($Submit for $2$ points, so $4$ points total$).$

Enter integer: $4$

You entered: $4$

$4$ squared is $16$

And $4$ cubed is $64!!$

$(3)$ Extend to get a second user input into userNum$2.$ Output sum and product. $($Submit for $1$ point, so $5$ points total$).$

Enter integer: $4$

You entered: $4$

$4$ squared is $16$

And $4$ cubed is $64!!$

Enter another integer: $5$

$4+5$ is $9$

$4*5$ is $20$
