You are to write a program that generates the second, third, and fourth powers of a list of

whole numbers from 1 to n where n is input by the user. Write a Java program to do this.

First, ask the user for the largest of the whole numbers to use (n). Second, output the

column headers (see below, n, n^2, n^3, n^4). We can use the \t tab escape character to

line things up. As in :System.out.println(n \t\t n^2 \t\t n^3 \t\t n^4);

Next, use a for-loop to iterate from 1 to n, that is, write a counting for-loop that starts at 1

and counts to the users input n. Each time through the loop compute the four powers for

the current value of your loop counter variable. Once you have calculated all 4 powers,

print them out separated by two tabs so that they line up with the headers printed prior to

the loop or you can use System.out.printf to line arrange the output in columns. The sample

below assumes that the user entered the value 5 for n.

Test your program with different input values such as 5, 10, 1, 0 and -1. For 0 and -1, you

should get no numeric output at all. If you wrote your loop correctly, that will be the case.

Debugging tip:

If you get incorrect results when running code that contains a loop, place

some print statements inside the loop to print the values of any variables that you think

might be involved in the errors. This helps you check what your loop is actually doing.

----------

Write one additional program which itself contains two loops. You will have to decide

which loop type to use and how to write each one. Both loops will have a loop body that

consists of a computation and an output.

Loop 1: sum up all of the values from 1 to 10, outputting the sum (and only the

sum) as you go. For instance, it will output 1, 3, 6, 10, etc (on separate lines).

Loop 2: sum up all of the values of Integers starting at 1 and continuing until the

sum is greater than 200, again outputting results as you go.

It is up to you to decide what type of loops to use and how to write each, and what other

variables and instructions are needed in your program.
