Question

Write an application whose main() method holds two integer variables. Assign values to the variables. In turn, pass each value to methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared(). Create each method to perform the task its name implies (for example, displayTwiceTheNumber given the value 10 should display the following: 10 times 2 is 20 Part B: Modify the NumbersDemo class to accept the values of the two integers from a user at the keyboard. Output the answers to the console.

Answer 1

I'll provide you with the pseudocode and explanation of what's happening, and you can implement it in the language of your choice!

Part B requires seeing the `NumbersDemo` class. But if you want to get data from the user, you will need to use the appropriate library and functions. For example in Java you would need the Scanner class. Check this: https://www.w3schools.com/java/java_user_input.asp

It might be difficult to read with the comments, so try take them out and read the code! It's good practice :)
