$1\mathrm{.}37$ Basic output with variables $($Java$)$

This zyLab activity is intended for students to prepare for a larger programming assignment. Warm up exercises are typically simpler and

worth fewer points than a full programming assignment. Warm up exercises are ideally suited for an in$-$person scheduled lab meeting or as

self$-$practice. The last section provides a full programming assignment.

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 $20$

Run your program as often as you'd like, before submitting for grading. Below, type any needed

input values in the first box, then click Run program and observe the program's output in the

second box.
