Write, compile and execute a computer program which will define and initialize two hard - coded arrays ( subscripted variables ) and then populate a third array with the product of the two earlier declared arrays. The program will simulate the business application of examining a price, quantity and amount analysis using this simple but important equation. PLEASE PRINT OUTPUT!
Amount = Price × Quantity

I need to modify the working program by including, within the display() method a separate for loop that will display the following table, which shows the amount status as either being above or equal to $ 100.00 or being strictly below. Make sure that the program has four arrays and when completed, submit the program source code as well as the program outputs showing the results of running the code.
$ 100.00 . Store the status character in a global array defined as statusArray() with \' A \' for ABOVE and \' B \' for BELOW.
1) B
2) A
3) B
4) A
5) A
6) A
7) B
8) A
9) B
10) B
