1.13 Warm up: 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: 4You 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: 4You entered: 44 squared is 16 And 4 cubed is 64!!
(3) Extend to get a second user input into userNum2. Output sum and product. (Submit for 1 point, so 5 points total).
Enter integer: 4You entered: 44 squared is 16 And 4 cubed is 64!!Enter another integer: 54 + 5 is 94 * 5 is 20}
