Question

:)

Problem: ??? Your task: implement in CH the algorithm solution shown below. Then analyze it and explain, using just one or two sentences, what it does. Write this explanation as a comment at the top of your program. This explanation will be worth 5 points of your total grade. Do not be too detailed (for example, do not write it opens a file and then declares variables, and then reads from a file...), it should look like the problem descriptions in my previous lab assignments. Part A (70 points) Algorithm solution (in pseudocode): 1. Declare a Named Constant called MAX SIZE initialized to 50 2. Declare a Named Constant called TAX PERCENT initialized to 0.0825 3. Declare an array called item that holds text indexed to MAX_SIZE and initialized to empty space 4. Declare an array called price that holds double-precision real numbers and initialized to 0.0 5. Declare variable subtotal, total, and tax that hold double-precision real numbers and initialized to 0.0 6. Declare variable called no_of_item and index that holds integers (whole numbers) and initialize it to o 7. Prompt "How many items would you like to enter (Max = 50)?" 8. Get the value from the keyboard and store it in no of item 9. If(no_of_item is equivalent to 0) 10. Print "There are no items in the list..." 11. Otherwise if(no_of_item is less then 0 or greater then 50) 12 Print Number of items has to be between 0 and 50..." 13. Otherwise For(index=0 to no_of_item - 1) 15 Prompt "Enter the index +1, "item: Get the values from the keyboard and store in item and price at position of index End For 18 Initialize index to 0 While(index is less then no_of_item) 14. 16 17 19

This application takes item name and price of that item and store them
in parallel arrays, After getting input, It calculates subtotal of items
, tax on subtotal and total. After calculating, It prints the final report
