A prime number is an integer that is divisible only by 1 and by itself. Write a program that: 1. Takes a number as an input.

2. Prints back to the console all the primes that are larger than 1 but not larger than the number that has been entered.

You need to have a procedure called isPrime. You may have more procedures if you like.

1. This procedure receives a number through one of the registers.

2. Checks if this number is prime.

3. Returns back through one of the registers to the main program 1, if the number is prime, 0 otherwise.

sample run:

Please enter a number: 44

Primes found until the given number:

2 3 5 7 11 13 17 19 23 29 31 37 41 43 Press any key to continue . . .

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.

The file sales data. xlsx contains monthly sales amounts for 40 sales regions. write a sub that uses a for loop to color the interior of every other row (rows 3, 5, etc.) gray. color only the data area, columns a to m. (check the file colors in excel. xlsm to find a nice color of gray.)
